The Pre-Season Rhythm: Where Vietnamese Football Writes Its Season in Advance

The fourth training session of the week. At 8:40 p.m., the side pitch at the national football training centre in Nhon still had one figure on it. A twenty-two-year-old centre-back placed two plastic cones about fifteen metres apart, stepped back, turned to receive the ball on his left foot, then played a long pass. The movement repeated. The groundskeeper leaned against a lamp post, a bunch of keys in his hand, and did not hurry him.

I counted forty-six repetitions in twenty-five minutes. On the forty-seventh, he stopped, breathed, and bent down to collect the cones. The floodlights went off. No stands, no cameras, not a single goal in that evening.

Vietnamese football, in most people's memory, is the light of the night of January 27, 2026, in Changzhou, when snow fell and the U23 team reached a continental final for the first time. It is the night of December 15, 2026, in Hanoi, when a 1-0 scoreline against Malaysia closed out an AFF Cup title after ten years of waiting. It is the first morning of Lunar New Year 2026, when the national team beat China 3-1 at My Dinh in the third round of World Cup qualifying.

I remember something else. People remember the goals. I remember the silences between two touches of the ball.

The context of this story is not on the league table. It is in the calendar.

V.League 1 currently has fourteen clubs playing a double round-robin, twenty-six rounds in total. Wedged in between are the National Cup, national-team windows, youth competitions, and continental cup slots. The result is a calendar year that can cram more than forty competitive matches into the legs of a first-choice player, travel not included. The season kicks off while the ground is still hot and ends when the heat returns.

The national team has passed through three head coaches in four years. Philippe Troussier took the job in early 2026 with a youth-rebuilding project, then left in March 2026 after two defeats to Indonesia in the second round of 2026 World Cup qualifying — 0-1 in Jakarta on March 21 and 0-3 in Hanoi on March 26. Kim Sang-sik was appointed in mid-2026. On January 5, 2026, in Bangkok, Vietnam beat Thailand 3-2 in the second leg of the ASEAN Championship final, winning 5-3 on aggregate and reclaiming a regional title after six years.

In that match, Nguyen Xuan Son broke his leg in the first half. It is a detail very few people want to recall, because it does not appear in the celebration footage.

Based on my experience covering matches and training sessions across many seasons, I believe the prevailing way of reading Vietnamese football is focused on the wrong thing. People read results. What needs reading is rhythm.

Back to the pitch in Nhon. What I observed there was not talent. Talent is visible to everyone the moment he scores. What I observed was the ability to repeat a movement at low intensity while tired. A centre-back playing a long pass with his left foot after two hours of work under a Hanoi July sky — that is data about a tolerance threshold, not data about technique.

A training ground never lies. It only whispers to those who stay behind.

Over the past three seasons I have logged a fairly clear trend in V.League 1: the number of high-pressing sequences in the first twenty minutes is up, but the quality of the thirtieth pressing sequence onward drops sharply. In other words, teams have learned to start matches at continental intensity but cannot sustain it beyond the first half. The cause lies in accumulated physical foundations, and those foundations are built in pre-season — the phase almost nobody watches.

Here is the crux. The difference between a Vietnamese team that reaches the third round of World Cup qualifying and one eliminated in the second round is not player quality; it is whether that team went through a complete physical preparation phase. In any season where the calendar is compressed by a regional tournament, clubs lose roughly three to four weeks of pre-season. Those three weeks are never recovered.

I once wrote that stumbles in the Champions League begin in August. In Vietnam, that proposition holds in a different way. The stumbles in the second round of 2026 World Cup qualifying began in July, in training sessions with no spectators, when the team could not build an aerobic base because the fixture list had already taken the pitch.

Now let us talk about what I believe is the most misjudged thing in Vietnamese football today: the goalkeeper position.

In recent years the debate over the national team's number one has revolved around a single criterion — ability with the ball at his feet. Dang Van Lam, Nguyen Filip, Bui Tien Dung: each name is weighed on completed passes and on involvement in building out from the back. That is a reasonable criterion. But it has become the only criterion, and that is where it goes wrong.

I watch goalkeeper sessions at various centres. What I find is this: the volume of close-range reflex work — the shots a keeper must react to in under half a second — has fallen at most clubs. Meanwhile the volume of footwork and distribution drills has risen markedly. The balance has tipped. And when it tips, it tips toward the less important side.

At Southeast Asian national-team level, where matches are often decided by one chaotic moment in the box, one close-range finish, one scrambled corner — the decisive skill is still reflexes. Not feet. A goalkeeper with average distribution but outstanding reflexes still produces more points than a goalkeeper with outstanding distribution but declining reflexes. Yet the market value of the second group is higher. That is a pricing anomaly the market has not corrected.

I am not blaming any goalkeeper. I am simply recording that the selection criterion has drifted away from match reality, and in competitions where a single conceded goal can end a campaign, that drift is expensive.

Back to the bigger picture. Nguyen Xuan Son is a perfect illustration of both the strength and the weakness of the current model. He came up from the second division, was naturalised, scored relentlessly, and became the centre of the attacking game during the ASEAN Championship campaign. Then he broke his leg in the second leg of the final. A team that depends on a single striker will watch its entire attacking structure collapse along with that man's bone.

Something similar has happened before. Nguyen Quang Hai was the creative centre for years. Nguyen Tien Linh is the default target of every cross. Do Hung Dung is the rhythm of midfield. When any link in that chain is absent, the national team does not lose a player — it loses a function.

One note does not make a piece of music. One match does not make a football life. And one player does not make a system, however much the highlight reels want you to believe otherwise.

The academies are trying to close that gap. PVF, the national football training centre, and the academies of Viettel and Hoang Anh Gia Lai have all produced cohorts with better technical foundations than the previous generation. Nguyen Dinh Bac and Nguyen Hoang Duc are names showing that current is flowing. But that current is still not deep enough for a national team to rotate without losing its structure.

There is one measure I like to use when discussing squad depth: the number of players who can start without changing how the team operates. At leading Asian sides that number usually runs from fifteen to eighteen. In Vietnam it usually stops at eleven or twelve. The rest are contingencies, not alternatives.

The gap between eleven and fifteen is not a gap in talent. It is a gap in the number of elite minutes a young player accumulates before his twenty-second birthday. And those minutes are decided by club coaches, who are under results pressure every single round.

There is a closed loop here. Club coaches need points to keep their jobs, so they pick experienced players. Young players do not play, so they do not develop. The national team lacks depth, so it depends on a handful of stars. The stars are overloaded, get injured, and the loop restarts.

In seven seasons on the sidelines, I have seen this loop in several football nations. It does not break itself. It breaks only under an external shock — a regulation, a crisis, or a generation good enough to force its way onto the pitch.

The second shock Vietnamese football needs to confront is not on the pitch.

In recent years, sports betting in general and esports betting in particular have grown at a pace far exceeding the pace at which regulatory frameworks mature. In traditional football, monitoring, investigation and enforcement systems took decades to develop. In esports, that timeline is compressed into a few years, while the money does not wait.

I say this not to equate the two fields. I say it because the mechanism is identical: when betting money moves faster than supervisory capacity, the integrity of competition is the first thing eroded, and it is eroded quietly. No stand cheers when a match is sold. No clock marks the instant a player decides not to run that last yard.

For Vietnamese football, the lesson lies elsewhere. As competitions expand, as broadcast and prize money grow, pressure on integrity grows in direct proportion. Governance capacity must run ahead of the money, not behind it. That is a less glamorous investment than signing a striker, and therefore it is usually postponed.

Keeping rhythm, for me, means counting what no one hears.

At this point I need to say plainly something outside observers often skip.

The popular telling of Vietnamese football comes in two versions. Version one: a golden generation appeared, and everything changed. Version two: a foreign coach arrived, and everything changed. Both are appealing, both are easy to tell, and both locate the cause in a single point you can photograph.

Both ignore the largest variable.

That variable is the calendar. Not the fixture list in the sense of a table, but the time structure of a Vietnamese football year: when a team gets to build its base, when it must compete, when young players are thrown in, and when they are pulled out. Every national-team success of the past seven years can be traced back to a specific preparation window. So can every failure.

The March 2026 defeat to Indonesia did not begin in Jakarta. It began with the team entering qualifying on an incomplete physical base and with a tactical structure in the middle of a change between two philosophies. Nobody can fix that in a three-day camp.

The Bangkok win of January 5, 2026 was likewise not a moment of improvisation. It was the product of a cycle in which the team had time, had suitable opponents for experimentation, and had a striker at the peak of his form. When one of those three conditions vanished — specifically when Nguyen Xuan Son broke his leg — the rest of the structure had to carry a weight it was never designed to carry.

None of what I have written is meant to diminish anyone. A keeper of rhythm does not take sides between winning and losing. I am only recording that when a football nation explains its successes by individual talent and its failures by individual error, that nation will never fix its own structure.

So which signals should be tracked?

First, the actual number of pre-season days each V.League 1 club gets before the opening round. If that number is under three weeks, the season will be decided by injuries rather than tactics.

Second, the minutes played by under-22 players in the first ten rounds. This is the earliest indicator of national-team depth two to three years out.

Third, the volume of reflex work done by goalkeepers at club level. If it keeps falling, the national team will keep conceding in moments no tactical model can explain.

Fourth, the speed at which the integrity-monitoring system matures. This is a category with no league table, no fans, and therefore the most easily postponed of all.

None of those four indicators appears on a scoreboard. All of them appear on the training pitch, in the medical room, in the fixture schedule, and in meetings with no cameras. That is why they get ignored.

When the new season kicks off, the stands will fill again. People will remember the goals. Some young player will score in the ninetieth minute and become the most searched name of the night. Some coach will be criticised for a late substitution, and some coach praised for a correct call.

In Nhon, the floodlights will still go off at nine. And someone will still stay twenty-five minutes longer, counting out forty-seven left-footed long passes, because that is a threshold nobody set for him except himself.

The Vietnamese season will not be decided on nights with big crowds this year. It is being decided right now, in the July heat, in sessions nobody counts.
