The Man at the End of the Bench and the Slow Rhythm of Vietnamese Football

On the evening of January 5, 2026, at Rajamangala Stadium in Bangkok, the television cameras caught the exact moment Nguyen Xuan Son went down on the grass. Vietnam were leading Thailand in the second leg of the ASEAN Cup final. The naturalised striker had just put the ball in the net. Then he collapsed, and the whole technical area rose to its feet.

I was sitting in front of a screen in Seoul, nearly four thousand kilometres from that stadium. What I remember most from that night is not the goal, and not the final whistle. It is the image of a substitute taking off his training top and running along the touchline while the stands behind him were still screaming the name of the man who had fallen. For the next ten minutes, Vietnam's national team had to answer a question no commentator was quick enough to answer: with the goalscorer gone, who holds the rhythm?

Vietnam won that match, won 5-3 on aggregate over two legs, and lifted the Southeast Asian trophy for the third time in their history. But by the way I read the game, that trophy was decided in the least-watched place of all: the bench. I learn more from the man at the end of the bench than from the man lifting the cup.

A May that was not calm

In May 2026, the Vietnam Football Federation appointed Kim Sang-sik as head coach of the national team, replacing Philippe Troussier. He arrived in uneasy circumstances. One month after taking the job, Vietnam were officially eliminated in the second round of Asian qualifying for the 2026 World Cup, finishing behind Iraq and Indonesia.

The real story sits outside the scoreline. Vietnamese football had once reached the third round of qualifying for the 2026 World Cup under Park Hang-seo, and had once beaten China 3-1 at My Dinh Stadium on a night when the whole of Hanoi stayed awake. The fall from there to the second round was a fall of system, not only of results. In the two qualifying defeats to Indonesia — 0-1 at home, 0-3 away — Vietnam did not lose for lack of technique. They lost because there was no second plan once the first plan had been read.

That is why I chose the bench as my subject. In modern football, squad depth has left the emotional zone. It is a tactical indicator: measurable, comparable, and predictable.

Where rhythm is measured in minutes

Back when I was a mid-level reporter covering V.League matches, I started adding a column to my notebook that no newspaper had asked for: the number of minutes the 12th to 16th player at each club actually played. Not the minutes they sat on the bench, but the minutes they ran on grass.

That column told a sad and repeating story. Most V.League clubs operate on eleven names and one coach. Substitutes enter the pitch in two situations: when the team is losing and needs another striker, or when the match has already been settled in the 80th minute. There is no third situation — the one modern football considers most important: sending a young player on in the 55th minute at 0-0, to make him responsible in a real game.

People look at the scoreboard; I look at the way they breathe when the ball goes wide of the post. A player sent on in the 85th minute never breathes that way, because he has never been placed in a situation tense enough to have to breathe.

Vietnam does not lack young players. Look at the U19 and U23 squads of recent years and the number of players good enough for the domestic league is not small. The problem lies elsewhere: whether they get to play, and in what circumstances. A 20-year-old with twenty minutes every three rounds cannot be called underdeveloped. He simply has not been tested.

The law gives more; the users take less

For several seasons now, Asian competitions have allowed five substitutions, split across a maximum of three windows. In theory, this is the condition for rotation, for easing the load on key players, and for opening the door to younger cohorts.

In the V.League, reality has gone the other way. I have watched enough matches to recognise a repeating pattern: the fifth substitution does not become an opportunity; it becomes a release valve. Teams keep the same spine until the 70th minute, then make two or three changes at once to preserve rhythm. Young players enter when the match no longer has much left to lose. They run a few minutes, receive an average rating, and start again from the bench the following week.

A rule that grants more opportunity does not automatically create opportunity. It only grants more power to the person who already decides who plays. At most Vietnamese clubs, that person is under short-term pressure for results.

This contradiction matters more than any debate about formations. A V.League coach understands that if he loses three matches in a row, the question of whether he will be sacked will arrive before the question of how many minutes he gave a 20-year-old. The incentive structure is not written in the tactical manual. It is written in contracts, in league-position targets, and in the meetings after every round.

The resources of V.League clubs come largely from their parent companies, not from broadcasting rights. When the budget depends on an owner rather than on a revenue stream, the measure of success also depends on one person. And that measure is usually read in the final table, not in the minutes of a 21-year-old.

Running in parallel is the age clock of the generation that carried Vietnam to the third round of 2026 World Cup qualifying. Do Hung Dung was born in 2026, Nguyen Quang Hai in 2026, Nguyen Hoang Duc in 2026. Over the next few seasons, this group will pass the far side of the slope. The gap they leave will not be filled by a training camp. It can only be filled by minutes accumulated over three or four seasons beforehand.

Naturalisation as an indicator

In the middle of that picture, Vietnam's use of naturalised players such as Nguyen Xuan Son, Jason Pendant Quang Vinh and goalkeeper Patrik Le Giang is a subject misread in both directions.

One side says it is a step towards professionalisation, that every major national team does it. The other says it is a sign that domestic football has run out of people. Both readings overlook an operational detail.

Nguyen Xuan Son was a striker with a finishing and pressing ability that, at that moment, nobody at home could replace. He won the golden boot and the best player award at the 2026 Southeast Asian championship, scoring in both legs of the final. Vietnam needed a player like that, and he arrived at the right time. But when he went down in Bangkok, the team fell straight back to the original question: if the man with the key is gone, can the system open the door by itself?

I do not see naturalisation as a sin or a miracle. I see it as a diagnostic indicator. When a system has to buy solutions instead of producing them, that indicator does not speak about the man who was bought. It speaks about the system that bought him.

The contrarian view

There are two popular readings I consider wrong, and I want to say so plainly.

The first holds that Vietnam's biggest problem is declining quality among young players, that the next cohort no longer produces names like Nguyen Quang Hai or Nguyen Hoang Duc. That conclusion does not hold, because the quality of a generation cannot be judged by what is visible in U23 matches. It is judged by whether that generation gets to play in a demanding enough environment. Players who have never been sent on at 0-0 have not been proven weak. They have only not been asked.

The second holds that changing the coach will change the system. Vietnamese football has cycled through several coaching changes in a single decade. The coaching carousel now spins faster than the cycle required to develop one player. When the carousel at the coach's seat turns faster than the carousel at the bench, nobody has enough time to turn a substitute into a starter.

Every season is a drumbeat, and my job is to listen until it becomes a melody. The current drumbeat of the V.League is fast where it should be slow, and slow where it should be fast.

Empty stadiums and empty benches

In 2026, when competitions stopped because of the pandemic, I went into the stadium twice a week and sat listening to the mower of Mr Kim Sang-oh, who had kept the pitch for fifteen years. No crowd, no goals, nothing to put in a bulletin. That series taught me more about reading football than anything else: the empty stadium that year taught me that noise is not football.

The bench is also an empty stadium. Nobody counts how many times a substitute warms up without getting on. Nobody measures the minutes he stands on the touchline in the cold of a northern evening. Nobody records that he is the last man to leave the dressing room after a defeat.

After heavy defeats, I learn more from watching the people who stay behind to clean up than from watching the scoreboard. They tell me how genuinely connected that team is.

Signals to track

The V.League season is entering its compressed phase, when clubs must play many matches in a short window and the national team needs a stable pool for continental qualifiers. That is the moment when the bench stops being a reserve story. That is the moment when the minutes of the 13th player become a technical indicator.

Over the next few rounds, I will track one number: the minutes played by players under 22 while the score is level. Not the number of players introduced on television, not the number called up to the national team. Just that number.

If it rises, Vietnamese football is building a system. If it stands still, we are building a starting eleven.

The best sportswriter is not the fastest runner, but the one who stays longest. I stay. And I am still counting.
