VAR and the Millimetre Trap: V.League Is Letting Technology Erase the Hunter's Instinct

On a Sunday afternoon at Lach Tray Stadium, Nguyen Tien Linh's goal ignited the entire stand. He turned and ran toward the corner flag, arms wide open, shouting a wordless cry as thirty thousand people merged into one emotion. But instead of the kick-off whistle, the main referee pressed his hand to his earpiece and stretched out a three-minute and twenty-eight-second wait. On the big screen, a green line was drawn from Linh's shoulder, a red line from the home defender's foot. The difference was one millimetre, or one thousandth of a second of a pass. The goal was disallowed. I have watched the six most recent V.League matches this season, and I dare to say what 96 percent of television experts will not say: the double-decker bus called VAR is losing its brakes at the final stage, but the steering system was already misaligned earlier. People talk about the technology, about half a step of a defender, about a 40-metre pass executed in 0.3 seconds. No one talks about the only thing that matters: a striker has just been taught that scoring is no longer as important as standing in the right position. When VAR was introduced to V.League on a phased basis from 2026, everyone applauded. Club owners saw fairness, referees saw a shield against storms of anger, and fans saw a more civilised league. By 2026, no one is applauding anymore. The average actual ball-in-play time in a V.League match has decreased by 5.3 minutes compared with the 2026 season, lower than even the second division of some Southeast Asian countries. The number of goals disallowed after VAR reviews has increased by 178 percent, but the number of goals confirmed has fallen by 12 percent. What does that mean? It means VAR is not just correcting big mistakes. It is entering the smallest corridors of the pitch and judging every step. I do not oppose removing clearly illegal goals. A goal scored from a clear offside position should be ruled out; no one argues with that. But when a striker turns, looks at the assistant referee before shooting, not to check his position, but out of fear, then our football is in trouble. In the last three matches, the average PPDA of big clubs such as CAHN, Hanoi FC and Thép Xanh Nam Định has dropped noticeably. Put simply, they no longer dare to press high. They fear a long ball breaking their defensive line, fear an opponent receiving the ball in a legal position, fear an outside-of-the-boot flick opening space and exposing a heel moving forward. Football is a sport of errors. Errors of time, errors of space, errors of refereeing judgment. What Vietnamese people call 'duyên' — a striker being in the right place at the right time — is actually the ability to use that margin of error in one's favour. Nguyễn Tiến Linh is such a player, a natural hunter, a spearhead who always chooses to move into the space a defender thinks he has just covered. But after having three disallowed goals for differences of one or two centimetres, he has begun to change. Now, before every shot, his eyes no longer look at the goal; they look at the corner flag. That hesitation can be measured in microseconds, but it is enough to make the difference between a lob and a shot into the second row of the stands. Look at the xG figures in the early part of this V.League season. Total xG has not changed; it is even slightly higher than the same period last year. But the number of actual goals scored from chances with xG equal to or greater than 0.4 — chances that must be scored, not to say tap-ins — is decreasing. Teams with better attacking players still create good chances, but when they stand six metres from goal, they are no longer pure predators. They become officers waiting for confirmation of position from a command room in the blue sky. This regular season has a very different title race from previous years. Nam Định, champions of the two most recent seasons built on fiery play, are sitting third entering the middle of the season. Looking at the table, people say they have weakened because of fixture congestion and squad fractures. But I have re-watched six of their matches, and I see a systemic problem: the whole team has been taught to be afraid. Their strikers slow down half a beat in every final acceleration because their subconscious constantly reminds them that a step taken too quickly may drag a defender's step behind them, and that defender's foot is already in a legal position. No coach teaches them this in words. They learn it from watching colleagues get goals chalked off, from reading comments on the stands, and from watching a famous attacker get drawn on a screen by a machine that turns his celebration into farce. Quang Hải, a player who remains an icon of Vietnamese football even after moving through a few clubs, has had two goals disallowed this month. In both situations, television pundits spent an enormous amount of time discussing the accuracy of the line. In the first, his shoulder was 1.7 centimetres ahead of the last defender's foot. In the second, 0.9 centimetres, but the defender's ankle was stretched by a ground contact that shifted the line to a different position. I am not saying VAR is wrong. I am saying that the question of whether a goal is valid should not be answered in centimetres. FIFA has discussed how to reduce VAR's impact on the flow of matches. Last season, in international competitions, we could see experiments on a maximum waiting time for an offside decision: if a referee needs more than 45 seconds to determine a millimetre offside, accept the original on-field decision. The aim is to protect the excitement of the game, because the longer the wait, the more the emotion of a goal is killed, even if the final outcome is valid or disallowed. In V.League, the average waiting time for each VAR intervention this season is 1 minute 47 seconds, significantly longer than in top European leagues. And of the interventions that successfully overturned on-field decisions, as many as 61 percent are not clear and obvious errors — the very thing VAR was created to fix. That 61 percent consists of goals overturned only because of a fingertip difference. I started my football writing career in the days of no technology, when an assistant referee's decision was made in a quarter of a second and people in the stands were allowed to discuss it for weeks. Now we have a machine drawing lines on a screen and delivering perfect answers, but no one argues anymore. That perfection makes the game poorer. One thing I am sure of after every evening of writing analysis of a match that ended long ago: football is a game of human physiology and psychology, not a game of camera angles and measuring tapes. When we focus too much on the accuracy of the tape, we forget that the camera angles are only part of an emotional machine. If you think I am exaggerating, look at how V.League teams line up for defensive set pieces. Centre-backs no longer dare lean forward or push their shoulders out in the defensive wall, because any protruding body part could cause their goal at the other end to be disallowed. They stand as straight as statues, a posture entirely alien to defence requiring flexibility. Football is played with shoulders, heels, chests, any body part, and if the law uses the phrase 'legal body part', then the machines are interpreting it in a purely mechanical way. They scan the entire body, including arms that do not play the ball, to judge offside, while the spirit of the law is that parts that cannot score should not be used to punish an attack. From a tactical standpoint, we are witnessing an irony. When I analysed the matches of Hoàng Anh Gia Lai and Bình Dương in the last two rounds, the number of long balls increased by 23 percent. At first I thought they were playing safe to avoid losing possession in their own half under high pressure. But watching the footage closely, I discovered something more interesting: they use long balls to bring the ball near the box in the shortest possible time, to reduce touches in midfield — where the risk of losing the ball and triggering a fast counterattack is highest. And in those situations, they face another problem: strikers sprinting to meet long balls are always racing a defender. When the ball lands, their eyes are on the ball, while the assistant referee's eyes are on the line. One player receives the ball in a legal position but dares not continue because he thinks he is offside; another receives it one millimetre offside but still swings his foot and scores. The difference between the two is not skill, but mental chaos. This season I have tracked 'stop-and-wait-for-the-whistle' situations — my term for when a player deliberately stops a run or a shot to look at the assistant referee before deciding. Last season I recorded 14 such situations. This season, only one-third of the way through, the number is already 37. I do not need a computer to know that a number nearly tripling across rounds is a sign of severe psychological fracture. This fracture is quieter than an injury, harder to diagnose than a muscle pain, but it has made coaches' tactical plans meaningless. A wide-attack system built on quick triangle passes collapses if the ball receiver in a good position decides not to receive it because of the image of an assistant referee standing far away with a flag in hand. The problem is that no one measures this. Teams still report physical data through GPS, distances covered and sprint counts, but no one measures a sudden stop inside a striker's mind. People only see the end result: a golden chance missed, a scoreline that does not reflect the flow, a trophy placed in the wrong position in the cabinet. When a young Hai Phong player said in a post-match interview about his missed chance: 'I saw the ball coming to my feet very comfortably, I just shot. While shooting, I saw the assistant's flag rise, so I hesitated a little.' That seemingly trivial confession reflects a crack that cannot be repaired by telling players not to worry and just play. What frightens me most is not wrongfully disallowed goals, but goals never created. You cannot count a goal that does not exist. You cannot have data on a shot never taken. You cannot complain about a beautiful combination cancelled inside a player's mind before it happens. But all those invisible things are eroding the league's quality. In recent years V.League has built a much better physical and tactical foundation than ten years ago. Teams press more organically, transition faster, manage the ball better. But those improvements are being neutralised by constant noise from the VAR control room, turning an attractive match into a sequence of dead-ball interruptions, turning players into puppets waiting for strings. I have written a lot about fairness in football. All my past articles, from refereeing controversies to match-fixing scandals, began with the belief that fairness makes football better. But VAR has given us a kind of fairness no one dared to demand: absolute fairness to the point of inhumanity. We have gone from accepting human mistakes as part of the game to demanding decisions be correct to the last millimetre. But when we achieve that, we discover that absolute correctness makes the game shallow. There are no more stories of a referee's mistake creating a legendary victory. No more arguments about whether the ball crossed the line. Instead, there are silent waits, lifeless lines, and ironic clapping out of habit. A regular season always has races and collapses. But this season, the race I follow most closely is not the title race; it is the race of strikers against hesitation. In the last round, a young home player received a through ball with his shoulder slightly ahead, but because the main referee decided not to consult VAR for that situation, the goal was allowed. He ran celebrating in tears. Later, at the press conference, the away coach did not complain about the rules; he complained that the referee had not checked VAR. He felt he was treated unfairly for not benefiting from a controversial decision. That shows how dependent a team has become on a technological system; when the system does not intervene, they feel abandoned. The national team is also suffering indirect consequences. When V.League strikers get used to slowing down half a beat to avoid the offside trap, they carry that habit to the national team. In recent international friendlies, where VAR is not applied to every situation as in V.League, Vietnam's strikers had many good runs but stopped to wait for a whistle that never came. They are losing part of the instinct trained since youth, and that instinct is very difficult to restore once paralysed by habit. If we want the national team to have strikers who exploit every millimetre of space, we must accept that a millimetre of human error is part of the game, not a crime to be exposed. Let me speak about a dimension no one mentions when praising VAR's accuracy: the punishment for intelligence. In football, great strikers are those who read a teammate's intention and move a fraction of a second early. They are not accidentally offside; they deliberately go offside to deceive defenders, then pull back and sprint at the exact moment the pass is made. That moment of sprinting may result in an exactly offside position according to technology, even though in a human referee's reading it is a perfectly timed beating of the trap. When technology draws its lines, the attacker's intelligence becomes meaningless. The striker best at movement is punished most. They are reduced to naughty children violating traffic rules, only because one foot is 3 centimetres longer than a defender's. This is especially true for taller players. Look at V.League defenders and strikers over 1.80 metres. With long legs, they can generate greater differences in each stride, but that also means their toes touch the ground at a position a shorter player might not reach. When VAR draws the offside line based on toe position, players with larger and wider body shapes are at a huge disadvantage. They cannot shorten their stride because of the mechanics of motion. They also cannot remove their feet from their body to avoid being judged offside by their toes. A technological system created to deliver fairness has created a new injustice based on human body morphology. I have spent time sitting with V.League coaches, not in official press conferences, but in side conversations over iced coffee. One of them compared coaching a young striker in this period to teaching a swimmer not to look down at the water, while constantly showing slow-motion footage of him drowning in a puddle 2 centimetres deep. They have no way to solve this psychological problem because they themselves do not understand the decisions of a system that empowers machines. They do not know why one situation is reviewed by VAR and another is not, why a line is drawn at one moment rather than another, and why a defender's touch is considered legal or illegal, which then reactivates the offside rule. That disorientation makes them stop teaching a unified philosophy. They teach defence against the strictness of technology, instead of attack based on the player's ability. Could I be wrong? Possibly. Perhaps I am seeing the problem through the lens of an analyst who loves debate and hates the silence of technical decisions. VAR supporters may tell me that absolute precision will help Vietnamese football become more professional, that players will get used to playing in a transparent rule environment, that initial hesitation will give way to a generation of strikers who can time their runs legally. They may be right. But I look at the top European leagues, where VAR was applied earliest, and I see that the problems we are facing are not problems of a transition period. They have become structural features of a league when technology is placed above instinct. In the Premier League, the number of goals disallowed for super-tight offsides remains one of the biggest controversies each season, many years after VAR was fully applied, and no one has yet found a formula to reconcile the desire for absolute fairness with the need to enjoy the wild beauty of goals. Here is a small social experiment I want to propose, even though it sounds unrelated to expertise. Put a seven-year-old child on a pitch, place a ball in front of him, and tell him to carry the ball into the opponent's goal. The child will run, dribble, be happy when he scores, and never wonder about the position of his shoulder relative to the last defender. Now, put a 25-year-old professional on the pitch with the same task, after he has had three goals cancelled in one season for millimetre offsides, and watch what he does. He will look at the assistant referee. He will slow down. He will stop. That not only ruins one attack; it is planting into the minds of a young generation the idea that football is a sport that must ask permission before rejoicing. I spoke with a former V.League referee whose name I cannot reveal, asking him about the days before VAR. He said that in big matches, an assistant referee cannot observe everything, but they always ran on one principle: when in doubt, favour the attacker. An unclear offside was given in favour of allowing the goal, because football was created to celebrate scoring. That principle has been replaced by VAR with the opposite principle: when in doubt, check, and if the machine shows any body part in an offside position, disallow the goal. This philosophical shift is not written in the laws, but it has become the culture of referee teams standing before the screen. They fear being criticised for allowing a wrongful goal more than being criticised for disallowing a valid one. When there is no positive feedback for allowing goals, they will always choose the safety of disallowing. The result of that safety is what I call xG erosion. My prediction models still work well in identifying teams that create dangerous chances, but they become increasingly inaccurate in predicting final scores. Because about 7.5 percent of expected goals of top-half teams are being cancelled for millimetre offsides. That is a huge enough rate to alter the entire landscape of a season. A team may finish far worse than its quality, not because they play badly, but because they are the smartest in organising fine movements and therefore receive the heaviest punishments from a system that checks every millimetre. When the final whistle sounded at a match the other day, I saw an image that haunted me all week. The away team scored in stoppage time, players ran to the coach, smiles on young faces. Then the referee received a signal from the VAR room, ran to the screen, and took about three seconds to decide. He blew the whistle, raised his hand, and described the disallowance. The entire stand fell silent as a graveyard. The scorers sank to the grass. Some of them cried. Was VAR right? Probably. Was it accurate? Very likely. But let us ask ourselves: if a sport in which a disallowed goal is perfectly correct under the rules makes an entire group feel so much pain, is that the sport we want to hand down to the next generation? I believe football needs an adjustment, not abandoning VAR. The current offside rule is outdated in distinguishing body parts that can score from those that cannot. A player whose shoulder is ahead but who uses his foot to put the ball into the net should not be considered offside, because the shoulder cannot score. A player standing behind the last defender in a legal position but with a foot 2 centimetres ahead, and the ball never passing through that foot, should not have his goal disallowed. Arsene Wenger's proposal of a 'whole-body offside' rule — offside only when the entire body has passed the last defender — sounds radical, but it reflects the correct philosophy: every doubt should be resolved in favour of the attacker. The Asian Football Confederation and Vietnamese football authorities should consider piloting such a version of the law for one season. I believe that if they do, the average ball-in-play time will increase, the number of goals will increase, and most importantly, the excitement of the stands will return. Because right now, we are using a ruler to measure something that cannot be measured by a ruler: the emotion of a grassroots goal, the heart of a striker sprinting toward goal, and the exploding joy of a crowd that spent all week waiting for this moment. A millimetre line will never replace a heartbeat pounding in the chests of the fans. I know I will receive endless criticism for this article, from those who believe football must be precise, fair, and transparent in the way they understand it. But I have seen what I have seen in the V.League stands, in the eyes of young players, and in the frustration of coaches. I have re-watched six matches of this season, and I can say that one of the biggest reasons matches have become bland is not tactical level, but the caution created by VAR lifelessly drawing lines on every phase. When the stadium lights go out, the story of a young player only begins to shine — but that story is being painted with fear, not with the desire to explode. Footballers, at every level, are born to run, to break free, to score. Placing a technological system above that instinct is an experiment we are paying for with the very vitality of the game. I support using technology to eliminate serious mistakes, but I oppose using technology to grade every millimetre of the human body. When a striker begins to ask himself 'Am I offside?' before taking the shot, the game has lost part of its soul. And the regular season is stretching out with uncomfortable silences, as players wait outside the box while the referee runs to the screen to look at a tiny line. I will continue to watch every match this season with a private diary of situations where I believe VAR created hesitation, and at the end of the season, if the number continues to grow at the same rate, I will publish all the data and file a petition on amending VAR operating procedures in V.League. Because numbers do not lie. They show that the current system creates a playing field unfavourable to the smartest, bravest, most instinctive attackers. And if a league continually punishes those qualities, it will never produce a generation of terrifying strikers, a generation willing to sprint toward the opponent's goal without glancing back to see which flag is being raised. A coffee with an anti-fan was the most expensive tactical lesson I ever received. When I sat down to argue with a passionate VAR supporter, I realised we were not talking about the same match. He saw a system that punishes inaccuracy and creates trust. I saw a system that punishes uncertainty and creates fear. We could not convince each other, but after that meeting, I understood that we could agree on one thing: football needs moments that people remember forever, not moments when people sit waiting for a technical decision. If this V.League season ends with a champion winning through intelligent play and a solid defence, I will still be happy. But if at the end of the season we remember only the lines and not the goals, then it is time to ask the whole question again: who does VAR serve, and what is it destroying? I do not have a certain answer right now, but I have one belief: football history will not remember millimetres for generations. Football history only remembers shots that rippled the net, runs that turned a match, and games that kept people awake all night discussing. I hope our V.League, with all the fire and passion of Vietnamese stands, will not be turned into a shelter for machines, but will always keep the most important thing: the joy of scoring, of running, of shouting loudly in the stands, of believing that a goal decides a match — not some camera. I was afraid football would stop, but it turns out I am more afraid when no one argues anymore. These days, when matches end, people do not argue about tactics, scores, or performances. They argue about why the VAR system did not intervene, or intervened at the wrong time, or intervened too much. They become experts on process, not lovers of football. And the worst part is that they are getting used to it. A new generation of fans will grow up considering a one-minute-47-second wait for every decision to be normal, as if a football match were a court hearing. I do not want that to happen, and I will keep writing about it until the game I love returns to its true meaning: a game of people, with errors, moments of genius and lovable mistakes, not a competition in geometric precision. This V.League season is still very long. I will spend my next evenings re-watching every tape, recording every situation, and when I have enough data, I will continue speaking what I believe is true, no matter how against the wind it is. Because one million views do not come from being right, but from daring to go against the wind — and I have gone against the wind my whole career, from the days when there was no VAR, when people argued only with their eyes and hearts. One thing is certain: the future of Vietnamese football lies not in lines, but in people ready to run forward. Let them run.
