Vietnamese Football: When Academies Become Transit Stations

The last training session before a national-team call-up is always the shortest and the coldest of the year. At a training centre in the north, I stood behind the wire fence watching the head coach split his squad for an eleven-a-side drill. There were thirteen players on the pitch, goalkeepers included. Three first-team regulars had been driven to the federation's training base at dawn; two others were lying in the medical room with ice bags strapped around their thighs. The pressing scheme the staff had spent eight matchdays building was collapsed into a half-pitch possession drill, simply because there were not enough bodies to reconstruct a three-line structure. The coach spoke to me in a voice as flat as a written report: “It will be four more weeks before we play the right way again.”

A match without a roar still tells you more than a whole loud season.

That scene repeats at many V.League 1 clubs, three or four times a year, and almost nobody writes about it because it is too ordinary to be news. People write about the ninetieth-minute goal, the save, the games that get called historic. Very few write about the thirteen men on the training pitch, and about the price a club pays for producing players good enough to be taken away.

V.League 1 is run by the professional football joint-stock company, with a calendar that typically runs from around August to June of the following year. Within those ten months, the league is cut into segments by FIFA windows, the AFF Cup, AFC Asian Cup qualifiers and the SEA Games. That is a structural feature of a football nation whose national teams operate at high frequency, not an administrative accident. But the consequences are concrete: the club that contributes more internationals loses more training weeks.

The revenue structure of most V.League clubs rests on team sponsorship and owner funding. Broadcast rights money is pooled through the league operator, ticket revenue accounts for only a small share of total income, and club commercial activity is largely tied to the image of a few prominent players. Inside that structure, selling a young player is not a bonus. It is a budget line. It sits alongside the shirt-sponsorship deal and prize money, meaning it belongs to the revenue a club must have in order to survive a season.

Vietnam's player supply is concentrated in a small number of pipelines. The HAGL-JMG academy was founded in 2026 and produced a first cohort including Nguyễn Công Phượng, Nguyễn Tuấn Anh, Lương Xuân Trường, Nguyễn Văn Toàn, Vũ Văn Thanh and Nguyễn Phong Hồng Duy. The PVF centre came into being in 2026 and opened its facility in Hưng Yên in 2026. Viettel, Hà Nội FC and Sông Lam Nghệ An each maintain their own branch, producing names such as Nguyễn Hoàng Đức, Nguyễn Quang Hải, Đỗ Hùng Dũng and Phan Văn Đức. For years, the national team has largely lived off those five pipelines.

Naturalisation policy adds another layer of complexity. A club can fill a gap in defence with a naturalised centre-back within months, whereas developing a domestic centre-back takes eight years. The fast option almost always beats the slow one, because contracts are short and performance pressure is measured matchday by matchday. Every position filled by a short-term fix is a position into which an academy player has no route. That is why some strong academy cohorts still leave — not for money, but because they cannot see a path to the first team.

And yet those same five pipelines are the entities that sell the most people.

In May 2026, Nguyễn Tuấn Anh went to Yokohama FC on loan. A few weeks later, Nguyễn Công Phượng joined Mito HollyHock. In 2026, Lương Xuân Trường wore the Gangwon FC shirt in K League 1. In 2026 the traffic peaked: Công Phượng moved to Incheon United and then to Sint-Truiden, Xuân Trường to Buriram United, Đoàn Văn Hậu to SC Heerenveen on loan. In July 2026, Nguyễn Quang Hải signed with Pau FC in Ligue 2. In January 2026, Nguyễn Văn Toàn joined Seoul E-Land.

Read as an honours board, that list looks excellent. Read as an attendance record, the story is very different. Based on my experience following these matches, what determines whether an overseas move has value is not the name of the league written into the contract, but the actual minutes on the pitch. Some deals ended with total first-team appearances in single digits. Some trips involved more time on the substitutes' bench than in tactical sessions with the starting unit. Đoàn Văn Hậu barely appeared for Heerenveen's first team. Nguyễn Công Phượng struggled for a starting place at Incheon. Those trips still delivered brand value and opened doors for later cohorts, but they did not produce a better player for the national team.

By contrast, Nguyễn Văn Toàn at Seoul E-Land is the model worth studying. He went to a high-intensity second division, played regularly, and preserved his match rhythm throughout his time at the club. The difference between the two groups sits in the preparation stage: one side had a playing-time plan agreed before signing; the other was built on the belief that a stronger league automatically makes you better.

For the club left behind, the problem is far harder. Selling an academy-developed player does not only remove a position from the squad, it removes two or three years of tactical construction. Players raised inside the club are the group that understands movement principles without needing to be retaught: when the midfield line pushes up, when the full-back tucks inside, when the striker drops to hold the ball. When they leave, the replacement may be fitter and technically equivalent, but he needs half a season to read the same book. During that period, the team usually drops points in matches it should have won.

Collapse does not come from a single conceded goal, but from hundreds of small details that were ignored.

Then there is the question of where the money goes. The training compensation mechanism and the sell-on clauses that apply when a player is transferred again exist within FIFA's regulatory system, and in several deals Vietnamese clubs have learned to insert resale terms. But in aggregate, most of the value created after a player leaves Vietnam does not return to the place that taught him his first passes. An academy spends hundreds of billions of đồng on facilities, fitness specialists and academic education over ten years, then receives a transfer fee just enough to clear one season of debt. That is the transit-station model, and a transit station cannot feed itself.

The most consistently overlooked part of the debate is the national-team window effect. Across a V.League season there are periods when a club loses between five and seven players to different national teams: the senior side, the U23s, the U19s. The club that loses players fields a patched-up line-up while the club that loses nobody fields its strongest eleven. The table, therefore, does not only reflect ability. It also reflects how many internationals a club has produced — and it reflects this to the disadvantage of the club that has done the best job.

I once checked this against distance-covered and sprint-count data for one club before and after a squad break. The gap was not in total distance but in high-speed sprints in the final thirty metres of the pitch. The players who stayed had to cover the spaces left by absent teammates, and the cost appeared two or three matchdays later in the form of muscle injuries or bookings from late tackles. This is the kind of data a league table does not show, and it is also the kind of data nobody sends to the coaching staff.

Speaking of data, this is where I have to be blunt about the analytics field. Metrics such as expected goals or passes allowed per defensive action work well when a line-up stays stable across dozens of matches. In V.League, line-ups change constantly because of transfers, national-team windows and congested schedules. A model calculating pressing intensity across a season in which the back four changes every six matchdays is measuring noise more than football. I am not against data analysis. I am against taking a model built for a high-stability league, using it to draw conclusions about a low-stability league, and then presenting that conclusion as objective fact.

The external picture is usually told differently. International media and most domestic media describe every overseas move as a step forward for Vietnamese football, and describe V.League as a nursery doing exactly its job. That framing skips two things. The nursery is never paid in full. And a league that takes pride in selling players while its own table is distorted by the very players it sold — that is a contradiction nobody has named.

The dressing room is where the truth outlives any contract.

I once heard a coach tell a young pupil that he should stay two more seasons. Not so the club could keep him, but so he could learn to take responsibility for a match. A twenty-two-year-old who has started two seasons in V.League and understands what it means to carry a game is a different player from a twenty-two-year-old with twelve reserve-team appearances abroad. What is notable is that the advice was given in a conversation where the club stood to benefit if the player stayed. It was still correct.

So which signals should be tracked from here? Three. How clubs structure player-sale contracts: whether there is a percentage sell-on clause, whether payments are tied to appearances, whether training compensation is explicitly written in. How the league operator handles the calendar in years containing SEA Games and qualifiers: if the schedule is still cut the old way, the problem lies in the design, not with any coaching staff. And how clubs invest in the second line: the club that builds a reserve squad good enough to play three or four early-season matchdays without collapsing is the club that lasts.

That season, I learned that the most fragile thing in football — form — is also the most durable.

One detail has stayed with me across years of watching training sessions. When a squad breaks for international duty, the ones who remain are usually the young players who have never been called up. They play matches nobody waits for, in front of stands not even a third full. If Vietnamese football wants to escape the transit-station model, the question is not how to keep good players at home. The question is how to let those who stay play inside a system stable enough for them to grow — and how to make the money earned from those who left return to the place that taught them to play.
