From My Dinh to V.League 1: Vietnamese Football Between Glory and Unfinished Promises

In the second leg of the 2026 AFF Cup final, Nguyen Xuan Son scored the goal that put Vietnam ahead, then fell. He lay on the grass, both hands clutching his knee, and the stadium went silent for a few seconds. The stretcher came on. A naturalized striker, the man who had carried almost the entire attack throughout the tournament, left the pitch at the very moment his team came closest to the trophy.

Vietnam still won. A 5-3 aggregate score over two legs against Thailand, and the first AFF Cup title since 2026 came home. The whole country took to the streets. But within that roar, there was one detail I could not take my eyes off: a team crowned thanks to exactly one player, at exactly one moment, and that moment nearly ended the career of that very player.

I have kept my promise to the stands since my first camera — every goal is a thank-you. That night, the thank-you was mixed with a professional unease I have carried through all my years in this trade: when a football nation celebrates, people rarely ask what had to be sacrificed for that moment. And for Vietnamese football, the answer lies somewhere few bother to look — not on the scoreboard of the final, but under the floodlights of V.League 1, where the annual season keeps drifting quietly by every weekend.

I live in Seoul and report on football for the Korean market. Born in France and raised between two cultures, I learned one thing: outsiders see the conventions that insiders no longer notice. With Vietnamese football, that distance is even clearer, because your national team is now led by a Korean coach, Kim Sang-sik. I followed him back in his K League days, and when he took the job in Vietnam, I began giving more weekends to a league most Asian viewers have never watched from start to finish.

A decade ago, Vietnamese football was a fairy tale. In 2026, the U23 team reached the final of the AFC U23 Championship, an unprecedented feat for Southeast Asian football. That same year, the senior team won the AFF Cup under Park Hang-seo, the first Korean to leave such a deep mark. In 2026, the team reached the Asian Cup quarterfinals. In 2026, for the first time in its history, Vietnam reached the third round of World Cup qualifying. Every milestone was a promise to the fans that this football nation would not stop.

But after the glow of the golden generation — names like Nguyen Cong Phuong, Nguyen Quang Hai, Doan Van Hau, Nguyen Tuan Anh, Vu Van Thanh, Nguyen Van Toan — came a silence. That generation was raised at the Hoang Anh Gia Lai academy, a project run with Arsenal and JMG, and they lifted the entire game to a new level. But as they entered their prime years, people began to notice something hard to say out loud: behind them, there was no matching generation coming through.

The Philippe Troussier period was a fracture. The French coach was expected to modernize the playing style, to move Vietnamese football away from counter-attacking toward possession. But the results on the pitch did not follow the ideas on the tactics board. The team failed in important tournaments, and public pressure forced him out. That was the first lesson in something Vietnamese football has still not solved: the gap between tactical ambition and actual resources.

Kim Sang-sik arrived in mid-2026 with a different philosophy. He did not promise a revolution. He spoke of balance, of rebuilding trust from the smallest things, and of a team that knows who it is. In football, a modest promise can sometimes carry more weight than a grand one. And the 2026 AFF Cup was the result of that modesty.

But a trophy does not erase the cracks beneath it. That is why I am writing this. Not to diminish the team's achievement, but to look at what produced it — and at what will decide whether it can be repeated.

Based on my experience covering V.League 1 matches over several recent seasons, one thing has become increasingly clear: the national team and the national league are running on two different tracks. One is the stage light, the blazing nights at My Dinh, the millions of fans. The other is the empty stands on a midweek evening, the clubs kept alive by a single corporate sponsor, the players who go months without wages and dare not speak up.

Let us start with Kim Sang-sik's system, because it is the brightest part of the picture.

The first thing he did in Vietnam was stabilize the defensive structure. He built a back three, with wing-backs pushing up the flanks and two central midfielders operating as a balanced pair. The shape was not new to Asian football, but the key lay in how it was operated. He demanded that the team defend as a block, not chase the ball, and, most importantly, know when to drop deep and surrender territory.

In the 2026 AFF Cup matches, I recorded a repeated pattern. Vietnam often let opponents hold the ball in the first half, keeping a low pass count but defending with strict positioning. In the second half, as opponents tired, the team accelerated. This is the strategy of a coach who understands he does not have a squad deep enough to impose the game for 90 minutes. He chose to win by managing energy, not by racking up passes.

The core of Vietnam's success at the 2026 AFF Cup was not in playing better than opponents, but in knowing exactly when to become dangerous. It is a form of tactical intelligence that Southeast Asian teams rarely display consistently.

Nguyen Xuan Son was the central piece of that system. This Brazil-born naturalized player brought what Vietnamese football had lacked for years: a striker who can hold the ball, link play, and finish inside the box. He did not just score. He changed how the whole team attacked. With him, midfielders knew that a long ball forward was no longer a lost cause but an opportunity.

But this is the point I want to linger on longer, because it is the essence of the matter. A team that depends on one striker is a team living on a fragile promise. Throughout the 2026 AFF Cup, when Xuan Son was on the pitch, Vietnam created chances at a markedly higher rate. When he left the field, the team lost its anchor and had to shift into a defensive mode to protect the result. That was no coincidence. It was a sign of a system without an adequate backup plan.

In other words, the trophy was built on the shoulders of one man, and those shoulders had just suffered a serious injury at the very peak of his career.

Behind Xuan Son, Vietnam's midfield has quality. Nguyen Hoang Duc is the kind of orchestrating midfielder rarely found in the region, able to hold the tempo and escape pressing with technique. Nguyen Quang Hai, though no longer at his youthful peak, remains a player capable of producing something out of nothing in tight spaces. Nguyen Tien Linh is a different kind of center-forward — less flashy, but effective inside the box.

But when I watch V.League 1 matches, I see a gap. The number of Vietnamese players aged 20 to 23 who are good enough to start at top clubs is shrinking. Teams tend to fill their squads with mid-level foreigners, or with naturalized players, rather than patiently developing their own. That is a rational choice for short-term results, but it is a loan taken against the future.

And this is where the economics of V.League 1 become important.

Most V.League 1 clubs live on a single main funding source — usually a company or a conglomerate tied to the owner. Broadcasting revenue is low, commercial revenue is limited, and matchday revenue accounts for only a small share of the total. That means when the parent company struggles, the club struggles too, and when the company loses interest, the club can vanish within a single season.

In recent seasons, Vietnamese fans have watched clubs with proud traditions dissolve or change hands, sometimes mid-season. Players under contract at those clubs suddenly become free agents with no preparation. This is a systemic risk that no professional league should accept in the long run.

Thep Xanh Nam Dinh is a notable example in the opposite direction. The club has risen to win the national title in recent seasons, with a relatively methodical investment project and a renovated stadium to attract spectators. Cong An Ha Noi is another emerging force, with clear resources and ambition. But when two or three clubs concentrate most of the resources, the rest of the league weakens, and overall competitiveness falls.

In the transfer market, I observe a familiar pattern. Every window, a few Vietnamese players are rumored to be moving abroad, usually to Japan, Korea, or Europe. Some do go, and succeed. Nguyen Quang Hai once played in France for Pau FC. But most of the remaining deals stay at the level of rumor, and those rumors are often generated by player agents to inflate prices or gain leverage in negotiations.

The transfer market is a flow of numbers, but it is also where dreams change shirts. And I have to be blunt: player agents are the biggest hidden cost in the Southeast Asian market. When a young player has a good season, agents appear, generate stories of foreign interest, and push expected wages far above real market value. The result is that clubs pay the price, players bear the pressure, and money that should have gone to youth development is redirected into commissions.

I do not say this to accuse any individual. I say it because I have followed similar deals in many football nations, and the pattern is the same. When information is not transparent, noise replaces truth. And when noise takes over, the ones who lose in the end are always the fans — the people who pay to watch a match, not to read a transfer story.

This is where I want to talk about the stands, because that is the part of Vietnamese football that does far better than many others.

Vietnamese fans are among the most passionate and loyal supporter communities in Asia. During the pandemic, when leagues were suspended and stadiums closed, I learned to hear applause from empty stands. In Korea, where I live, K League clubs placed cardboard cutouts of fans on seats to fill the void. In Vietnam, clubs did the same, and fans wrote letters, shot videos, and sent messages to players. That is a kind of affection you cannot buy with sponsorship money.

But here is the paradox: that very community is the smallest revenue source for the clubs. Tickets are cheap, licensed merchandise is underdeveloped, and the matchday experience is not commercialized to its full potential. A football nation with millions of fans that cannot turn that love into sustainable revenue is still leaving an enormous resource on the table.

This is the counterintuitive point I want to raise, because it runs against the general feeling after the 2026 AFF Cup.

That victory is told as a fairy tale: an underdog team overcoming adversity, a naturalized hero shining, a modest coach bringing the team home. And it truly is a beautiful story. But fairy tales in football tend to be consumed and discarded. People watch, people cry, people share, and then people forget. And what is forgotten most is the very structures that produced the story — or the structures waiting to break it.

For Vietnamese football, there are three cracks the trophy cannot hide.

The first crack is the dependence on one naturalized striker. Nguyen Xuan Son is not the first player Vietnam has naturalized, but he is the most successful case on the pitch. That raises a question this football nation will have to answer: without him, what would the attack look like? Naturalization is a legal tool used by many countries. But if it becomes the main plan rather than a supplement, it is masking a problem in attacking development at the grassroots level.

The second crack is the generational gap. The golden generation of the Hoang Anh Gia Lai academy proved that long-term investment in youth development can transform an entire football nation. But that project was never replicated. Many clubs still prefer buying foreigners to building academies, because results in the table are measured season by season, while an academy takes a decade to pay off. When short-term rewards dominate long-term ones, real structural reform in resource allocation never arrives.

The third crack is the financial and governance foundation of the league itself. A national league where most clubs depend on a single company, where broadcasting revenue is low, where player rights are not fully protected, is a league living in a fragile state. The AFF Cup trophy does not make those clubs healthier. It only makes people temporarily forget that fragility.

This is where I want to return to my role. I am an outsider, from France and living in Korea. I have no right to judge Vietnamese fans for how they celebrate. But I have a responsibility, as a reporter, not to let the trophy become a curtain. The camera never lies, but it knows how to tell a story from many angles. And the angle few choose is often the angle of the man at the end of the bench, the young player who never gets on, the club staffer who has not been paid.

I once stood in a press conference that was nothing but male voices. The shock that year was not on the pitch, but in a press conference made up entirely of male voices. When I raised my hand to ask a coach about a selection decision, an older male colleague sneered and asked whether I had only just started watching football. I answered with data. I learned that in this trade, data is a woman's defensive wall. But I also learned that data only has value when it serves a real question, not when it is used to dress up a prejudice that already existed.

That is why I am careful when I talk about V.League 1. I do not want to turn data into cosmetics. I do not want to take a few possession numbers and assert something I already felt. If I say Vietnam's attack depends on Xuan Son, I have to show it in how the team moves with him and without him. If I say the league is financially fragile, I have to point to the revenue structure, not just to the clubs in trouble.

And this is what I see most clearly after several seasons of watching.

The biggest problem for Vietnamese football is not a lack of talent, but a lack of a system that keeps talent at home and helps it grow. This football nation produces players that all of Asia takes notice of, but it does not create enough of an environment for them to mature domestically. When a young player is good, he has two choices: go abroad with the risk of never starting, or stay home on a good wage with little challenge. Both choices carry a price, and the football nation pays it in the end.

This connects directly to Xuan Son's story. A naturalized striker in his prime can solve the attacking problem for two or three years. But after that? If no domestic striker of real quality is developed in the same window, the team returns to the starting line, with only a trophy in the cabinet and a lesson still unlearned.

I believe a club is not just a shirt color, but a promise repeated every match. And that promise only has value if it is kept on the days when no one comes to watch.

So which signals should be tracked this annual season?

First, look at the minutes played by under-23 players in V.League 1. If that number rises, it is a sign clubs are investing in the future. If it falls, it is a sign they are buying short-term results. This is the indicator I watch most closely, because it says more than any table.

Second, look at the revenue structure of the clubs. A club with three independent income streams will be more sustainable than a club dependent on one company. When Vietnamese fans buy shirts, buy season tickets, and come to the stadium regularly, they are directly building that foundation.

Third, look at how the national team plays without Xuan Son. That will be the real test of Kim Sang-sik's system. If the team still creates chances and scores, then the 2026 AFF Cup is the start of a cycle. If not, it is just a beautiful moment in a long journey still full of questions.

I am not writing this to dampen anyone's joy. That trophy is real, and Vietnamese fans deserve to savor it fully. But I believe love for a football nation is not measured by the nights of celebration, but by what we do the next morning. When the lights go out, when the stands are empty, when the annual season continues with matches few watch, that is when Vietnamese football is truly defined.

A player walks out of the tunnel, and I see the ten-year-old child inside him. That child does not dream of a trophy. He dreams of a pitch, a ball, and a future where he gets to play football where he was born. The task of the adults — the federations, the clubs, the sponsors, and those of us in this trade — is to turn that dream into a road worth walking. Not with a single moment, but with a system.

The 2026 AFF Cup proved that Vietnamese football knows how to win. The question of this season is whether it knows how to keep that win — not on the scoreboard, but in the structures, in the people, and in the promises repeated every weekend across the country.
