Vietnam U23 fly to Japan after a single training session: the story is in the calendar, not the tactics

On the afternoon of September 12, on a training pitch with no stands, twenty-one players in red shirts formed a circle in the middle. That evening, buses took them to the airport. The overnight flight to Japan landed at about six in the morning on September 13. Three days later, on September 15, they play their first match.

That afternoon session was the only session this group has had together before entering a continental tournament.

I once stood for a long time under the stands at Hoa Xuan stadium during the days the V.League was suspended by the pandemic, when twenty-five thousand seats were empty and nobody clapped. A pitch never lies; we are simply not slow enough to hear it. That day I heard something I could only name much later: a team is not measured by what it declares, but by what it manages to do before the opening whistle.

This time, what they managed to do was one training session.

The chronology needs retelling, because in this story the chronology is itself the main character.

On September 12, fifteen players were present from midday. Six others came straight from the Hanoi versus Song Lam Nghe An match — five from Song Lam Nghe An, one from Hanoi. Two more flew on a later flight, on September 14.

Reading that sequence back, I notice something usually overlooked: this group is three sets of people travelling on three different routes, and they will only be fully together about one day before the opening match.

The men's football tournament has fifteen teams in three groups, running from September 15 to October 3. Olympic Vietnam are in Group C with Kuwait, the Philippines and Uzbekistan, based in Nagoya. The schedule is squeezed into eight days: Kuwait on the 15th, the Philippines on the 18th, Uzbekistan on the 22nd.

The target published by the Vietnam Football Federation before departure is a quarterfinal place. Before that, the Federation's General Secretary visited the squad to offer encouragement. I notice how these targets are always announced first, while the conditions for achieving them are announced later, or never.

The centre of this story sits in the calendar.

A national team entering a continental tournament usually has two to four weeks in camp. In that window a coach can install a defensive block, shape build-up from the back, rehearse set pieces and — above all — let players collide with each other often enough that a ten-metre gap between two heads becomes an unthinking reflex.

One session does none of that. It is enough for the staff to count bodies, check fitness and assign rooms. It is not enough to teach a centre-back when the man beside him will step up.

The real point lies in the player-release mechanism: while V.League fixtures still run right up to the day the national team departs, player quality becomes the secondary variable and time becomes the primary one.

Six players came straight from a competitive match. They played the full ninety minutes, changed, boarded a bus to the assembly point, then boarded a plane. Between that match and the Kuwait game lies less than three days, including a night awake in the air.

I have followed Vietnamese football long enough to trust a fairly simple rule: soft tissue does not read the results table, it only counts hours of sleep. If you wanted to build an ideal setup for injury, this is close to it — a tight match, overnight travel, different humidity, a different time zone, and a session immediately on landing so the staff can finalise the matchday squad.

The two players flying on the 14th carry one more disadvantage. When everything is new — new pitch, new ball, new opponents, new daily rhythm — those twelve hours are enough to create a gap. I do not expect them to start on the 15th.

The order of opponents also matters. Kuwait are a West Asian side leaning on physicality and long balls, the type of opponent Vietnamese youth teams have historically found awkward. The Philippines are a familiar regional foe. Uzbekistan are the strongest team in the group. When the first match is hard because legs are not yet in rhythm, the second is a must-win and the third is against the best side, the margin for error is very narrow. A draw on the 15th could turn the 22nd into a knockout game.

So how will Olympic Vietnam play? I will not answer by drawing a formation. No formation has been published, and any description of how the side will operate is speculation. But one route is sensible in these conditions, and it is the route almost every team short of camp time takes: a low block, short distances, prioritising transitions over long spells of possession.

That is the only asset a single session cannot take away: clusters of players who arrive from the same club, carrying reflexes already built. People remember the name of the scorer, but I remember his run ten seconds earlier. In a squad assembled in two days, the most memorable moments will be the ones that need no rehearsal: a pass between two club teammates who understand each other before the ball rolls.

Here I want to step away from the current of the news, because there are two places I think are being misread.

The first is the number of teams. The report states fifteen teams in three groups, with the top two from each group advancing to the quarterfinals. Three times two is six. Six teams cannot fill an eight-team quarterfinal bracket. So either additional third-placed teams progress, or the group and team counts are misreported. The detail sounds minor, but it determines how many points Olympic Vietnam need, and whether the Uzbekistan match is decisive or merely a chance to rest legs.

I have never seen a fan stripped of the right to support because they misread a format. But I have seen plenty of pointless arguments erupt simply because nobody checked the regulations before shouting at someone.

The second is the comparison with 2026.

That year Olympic Vietnam reached the semifinals and finished fourth under coach Park Hang Seo, and the memory has become a kind of national asset. But that 2026 group was a special generation, camped for long stretches, prepared through consecutive tournaments, with a core that ate meals together for years. Lifting the memory of a squad raised on time onto a squad assembled in two days creates pressure without creating information.

I remind myself of this when writing about Luka Modric and the seventy-two kilometres he ran in Russia in 2026: a number only means something when you know the circumstances that produced it. Seventy-two kilometres from a well-rested side differs from seventy-two kilometres from a side that just flew overnight. The heart keeps beating even when nobody is clapping in the stands — but how fast it beats still depends on whether the legs have slept.

There is a neglected part here, and it is the part I most want to say: the two who flew later.

They are not at fault. Their clubs are not at fault. None of these people chose a late assembly. The glory of the defeated is a light only those who stay behind can pick up, and in this case those who stay behind are two young players who may sit on the bench on the 15th, watching teammates play the opening match of a tournament they also helped reach.

If Olympic Vietnam lose to Kuwait, the one-training-session story becomes a shield. If they win, it becomes a legend. Both outcomes favour the adults, and both are meaningless to the young.

After reading through all these numbers, what I keep is a question about how Vietnamese football schedules itself. When a continental tournament falls outside the official club calendar, the right to release players sits with the clubs, and the national team receives only what is left. As long as that repeats, we will keep reading articles like this one, every two years, with the same headline and the same regret.

I do not expect change this week. But I will watch one more detail: who wears the captain's armband on the 15th. A list of twenty-one names does not say who leads, and when a group has had only one session together, the captain is the only person holding the thread while the staff are still dividing the lines.

When it is silent, I hear a whole generation waiting for something mad. In Nagoya on September 15, the silence will last about ninety minutes. I will sit and listen to all of it, and this time I will not count goals. I will count how often a Vietnamese defender turns his head to find a teammate, because that is the one thing a single session can teach, and the one thing it can also leave forgotten.
