The Five Percent Nobody Claims: FIFA's Solidarity Mechanism and the Legal Blind Spot in Vietnamese Football

When Đoàn Văn Hậu put pen to paper on a loan move to SC Heerenveen in September 2026, the Vietnamese press celebrated as though a great door had opened. Hà Nội FC was named as the pioneer. Few noticed that the paperwork for that deal contained a clause FIFA had long since written into its rulebook: the solidarity mechanism. When a player is transferred internationally, 5% of the transfer fee must be distributed to the clubs that contributed to his training between the ages of 12 and 23. The money is expressed as a percentage, calculated by a transparent formula, and systematically forgotten in the V.League.

Over years of re-reading transfer files in Vietnamese football, I have reached one conclusion: most of the value lost does not come from failed deals, but from money that should have been claimed and never was. Fans remember goals; I remember clauses. And the clause here is perfectly clear.

Vietnamese football lives inside a familiar paradox. At the top, V.League 1 has clubs backed by wealthy owners willing to spend on an expensive contract but far less interested in building sustainable revenue. The league's broadcasting income remains modest by regional standards, sponsorship depends on personal relationships, and club budgets are tied to the fate of one individual. The structure produces a predictable outcome: when the owner withdraws, the club wobbles; and when the club wobbles, young players are the first assets sold off.

Alongside that, the flow of Vietnamese players abroad has become part of the success story. Nguyễn Quang Hải joined Pau FC in France's Ligue 2 in 2026. Nguyễn Công Phượng played for Mito HollyHock in Japan and Incheon United in South Korea. Đoàn Văn Hậu had a short spell at SC Heerenveen. Every time a player departs, the media tells the story of the overseas dream. Behind that dream sits a financial mechanism Vietnamese clubs barely exploit: FIFA's solidarity mechanism and training compensation.

The two mechanisms must be distinguished. Training compensation applies when a player is transferred internationally for the first time after his contract with his former club expires, and it concerns only players under 23. The solidarity mechanism applies to every international transfer, including for older players, and allocates 5% of the transfer fee to the clubs that trained the player between 12 and 23, in proportion to the years served. Two different clauses within one system, and both can bring money to Vietnamese academies.

The problem is who takes responsibility for pursuing that money. In an international transfer, the buying club is obliged to calculate and distribute training compensation within 30 days of registering the player. But that obligation is only enforced when the selling side — or the beneficiary — knows it has a right. If no one files a claim, if no one cross-checks, the money simply sits in the system. In Europe, clubs have legal departments dedicated to tracking every academy transfer. In the V.League, most clubs have no legal office, no one monitoring FIFA's database, and no habit of sending a demand letter.

I once revisited a case to understand why this drags on. A Vietnamese player moved from a lower-tier club to a league in East Asia. The fee was modest, but under the solidarity mechanism his former training club was still entitled to a share. The trouble was that no one at the old club knew it had a right. When I asked, the answer was: "We never thought about it." Before pointing a finger at anyone, I ask myself whether I have read the whole contract. In this case, neither side had read the appendix.

The solidarity mechanism is not charity. It is money defined by law, with a formula, a deadline, and a dispute-resolution process. A training-compensation claim can be brought before FIFA's Dispute Resolution Chamber. The right exists; it is simply unused. That is a fundamental difference from the empty promises that circulate in football. An expired clause still speaks louder than an infinite promise.

Seen more broadly, this reflects a larger problem in Vietnamese football governance. V.League clubs typically operate under an all-powerful owner model. Who to buy, who to sell, what to pay is usually decided by one individual rather than a specialised apparatus. The model has the virtue of speed, but a fatal weakness: it skips processes that demand care, persistence and legal literacy. Chasing training compensation is such a process. It does not produce the glamour of a marquee signing, but it produces real revenue for the academy.

The solidarity mechanism carries another dimension: it encourages clubs to invest in youth development systematically. If an academy knows that every player it produces can generate money each time that player is transferred anywhere in the world, then investing in the academy becomes a calculable investment rather than a mere duty. In many countries, academies survive partly on this flow. Vietnam has an abundant supply of players and several generations going abroad, yet has not converted that advantage into cash.

There is a technical point Vietnamese clubs routinely miss: to benefit from the solidarity mechanism, a club must be able to prove the player's time with it between the ages of 12 and 23. That requires youth registration records to be complete and accurate. An academy that did not keep records ten years ago cannot prove its right, however deserving it may be. This is why the issue is both legal and operational. To claim money, you must first have the paperwork.

What is easily overlooked is the fans' emotion. When a Vietnamese player goes abroad, the natural reaction is pride. No one wants to think about a demand letter while watching their favourite player take the field overseas. But that pride, without systematic thinking, will repeat one script forever: the training club does the work, the buying club takes the benefit, and the money that should belong to the academy sits somewhere in the system. Emotion does not feed an academy. Only process does.

It must also be said plainly that the problem is not merely the awareness of individual clubs. League structure plays a role. When the V.League's collective revenue is thin, clubs must live on owner money, and they have little incentive to build a professional legal department. This is a vicious circle: no money means no specialisation, and no specialisation means missed money. Breaking that circle requires an approach at league level, not only at club level. The league organiser could play a central role in monitoring Vietnamese players' transfers abroad and supporting clubs in claiming their rights.

Looking ahead, one thing could change the picture. As more Vietnamese players go abroad, the value of each transfer rises. That means the 5% solidarity share becomes a more significant sum — enough for a club to take seriously. Academies that are well organised and have someone tracking the files will be the first to benefit. Those that do not will keep missing out. The gap between professional and amateur clubs will lie not only in player quality but in the ability to recover what the law entitles them to.

Vietnamese football has proved it can produce players good enough to play abroad. The next step is to prove it can recover the value it created. That is a legal contest, not an emotional one. And in that contest, whoever reads the contract carefully always holds the advantage.
