One Session, Three Waves, Eight Days and Three Matches: Vietnam U23 and the Preparation Problem at the Asian Games

One training session. That is the entire on-pitch preparation fund Vietnam U23 possessed before entering one of the most demanding youth tournaments in Asia. The session took place on the afternoon of 12 September, the very day the squad departed. No acclimatisation week, no centralised conditioning block, no internal practice match long enough for the coach to see how his back line reacts when the ball is lost in midfield.

At 6 a.m. on 13 September, an overnight flight put the delegation down at Kansai International Airport. One morning in Japan, exactly two days from the opening fixture. People usually talk about campaigns in goals, in possession percentages, in metrics a computer can read. Here, the most important metric was the number of training sessions. It was one.

Across more than half a century carrying a notebook from Tokyo to Rio de Janeiro, I have learned one thing: national teams do not win on raw talent. They win on prepared time. Time cannot be bought, borrowed or reimbursed. When you hand a young coach twenty-three players but only one afternoon, you have not handed him a chance. You have handed him an examination.

That examination is called the Asian Games.

Context: a tournament outside the FIFA window

Before going into detail, the context has to be reconstructed properly, because any analysis of Vietnam U23 at this Asian Games only means something once we understand the framework it sits in.

The Asian Games belongs to the Olympic Council of Asia, not to FIFA. This is the decisive point that many fans, and part of the media, routinely gloss over. Men's football at the Asian Games operates on a U23 framework with a limited number of overage slots, but it does not sit inside FIFA's official international match calendar. That means clubs are not legally obliged to release players. They release them out of goodwill, relationships and soft pressure, not because of an enforceable duty that carries sanctions.

That legal gap generates the entire story. Vietnam U23 flew twenty-one players on the main flight, with two more following on 14 September. Of the twenty-one on the first flight, six came straight from the club match between Hanoi and Song Lam Nghe An, five of them contracted to Song Lam Nghe An. They played a competitive professional match, then travelled overnight without a full recovery cycle.

This small detail is the nucleus of everything. In sports medicine, the soft-tissue injury risk window widens markedly in the forty-eight to seventy-two hours after a high-intensity match, particularly when sleep is truncated, time zones shift and long-distance travel is involved. Those six players enter the Asian Games not from a state of rest, but from a state of accumulated depletion.

In terms of timing, Vietnam's Group C schedule is compressed: Kuwait on 15 September, the Philippines on 18 September, Uzbekistan on 22 September. Three matches in eight days. The tournament runs from 15 September to 3 October. Venues spread across the Aichi and Osaka region, including Osaka, Toyota, Nagoya and Kariya.

And the target set by the Vietnam Football Federation, publicly restated by the federation's General Secretary before departure alongside words of encouragement, is a quarterfinal place.

One session. Three waves of assembly. Three matches in eight days. One quarterfinal target.

The distance between those four numbers is the whole story of this Asian Games.

Three waves of assembly and the price of a late ticket

People imagine a national team assembling like a ceremony: on the right day, at full strength, a group photograph, then work begins. At youth level, especially in Southeast Asia, it rarely looks like that.

Vietnam U23 assembled in three waves. The first wave, the largest, reported from midday. The second wave was the six players arriving straight from the Hanoi versus Song Lam Nghe An match, meaning they wore the club shirt before they wore the national shirt. The third wave was the two players retained by their clubs until 14 September, flying on a later service.

The consequence is concrete. The full squad was only genuinely together roughly one day before the opener. In football, one day is not enough to assemble a defensive block, let alone install a game model. One day is enough for the coaching staff to tell players which flank they occupy, who takes set pieces, who takes throw-ins.

I have recorded similar cases. In 2026, at a youth final on a dirt pitch in Nova Iguaçu, I watched a seventeen-year-old wearing number eight. He did not score, but he made eleven retreating runs to cover the right-back and held his distances almost perfectly. His team won 1-0 through a corner. Afterwards I did not interview him. I went to find the coach to ask about his individual tactical drills.

The lesson from that day remains intact: the things that make a team do not live in goals. They live in sessions repeated hundreds of times, until a player retreats without thinking. One session does not create that reflex. It only creates a note.

With three waves of assembly, what Vietnam U23 lack is not players. What they lack is collective reflex.

The two latest arrivals, flying on 14 September, will almost certainly enter the tournament out of sync both physically and tactically with the rest. The likeliest outcome is that they are used as impact substitutes rather than starters on 15 September. This is inference, not confirmed information, but it is inference with clear logic: a player who has never trained with his teammates is hard to trust with a starting berth in the opening match of a continental tournament.

Physical load: six names walking out of a real match

There is a distinction the media often fails to make: a player who trains a lot and a player who competes a lot are in two different states. Training a lot makes a player tired. Competing a lot makes a player worn.

The six players arriving from the Hanoi versus Song Lam Nghe An match had just been through a competitive official fixture. For the five Song Lam Nghe An players, this is not their first grind of the season across domestic competition and national-team camps. For the Hanoi player, it was a major fixture for a major club, meaning the psychological intensity was high too.

What matters is that they were not rested. They played, got on a bus, went to an airport, boarded a plane, landed in Japan, and two days later walked out for a continental tournament.

In sports medicine, this is the overlapping load pattern known as acute accumulation. The risk does not sit in the first match. It sits in the second and third, when the body has not fully recovered and must absorb another maximum effort. Vietnam's Group C schedule attacks exactly this weakness: the second match comes three days after the first, the third four days after that.

There is a detail I always record: teams short on preparation usually do not lose the first match. They lose the second or the third, and they usually lose in a way that makes viewers think it is a mentality problem. In truth it is a legs problem.

A team missing eight days of preparation will not pay the price over eight days. It will pay at the seventieth minute of the second match.

With five Song Lam Nghe An players and one Hanoi player fresh from a domestic fixture, the coaching staff face a choice between two bad options: start them and accept injury risk, or bench them and accept that the starting eleven is not the strongest available. Neither option is clean.

Geography: a four-city itinerary and the cost of movement

People talk about opponents and rarely about maps. But the map is part of the problem.

Men's Asian Games football venues stretch from Osaka to Toyota, Nagoya and Kariya. For a team based in Nagoya for the group stage, having group fixtures around a single base is a small plus: less movement between matches, a stable routine for recovery and meals.

But that plus is far smaller than the negative in front of it. To exploit the benefit of a central base, a team needs on-site training time. That time does not exist.

Moreover, as the group stage ends and a team advances, the itinerary widens, pitches change, grass changes, weather changes. Every change forces a team to re-adapt while opponents have long since adapted. Well-prepared teams use the pre-tournament window to familiarise themselves with different surfaces. Vietnam U23 used the pre-tournament window to board a plane.

The city is not loud; we simply have never listened to the sound of a ball rolling under a floodlight.

Group C: three opponents, three different questions

Group C contains Kuwait, the Philippines and Uzbekistan. On paper, the hierarchy is relatively clear.

Uzbekistan are the strongest name. Uzbek football at U23 level has for years run on a stable Central Asian development pipeline, with cohorts promoted early to senior football and tested in genuinely competitive environments. They are the highest-rated side in the group, and they are Vietnam's final group fixture.

Kuwait are a West Asian opponent with a physical, direct style, short on ornamentation but awkward to face. Historically, Vietnam's youth teams have not enjoyed matches against West Asian sides. This is the opener, only two days after landing in Japan.

The Philippines are a familiar Southeast Asian opponent. On paper, this is the fixture Vietnam are favoured in. Structurally, it is treated as a must-win.

That sequence creates an unhelpful psychological curve. The opener comes against an unpredictable West Asian side, with legs still heavy from travel and a defence not yet knitted. The second match comes against an opponent deemed beatable, which means maximum pressure. The third comes against the strongest side.

If Vietnam slip in either of the first two, the Uzbekistan match on 22 September could become a knockout-style decider. That is a scenario no coach wants, because it converts a tactical match into a psychological one.

For a team that has trained once, the most dangerous thing is not a strong opponent. The most dangerous thing is a must-win match arriving too early.

The shadow of 2026 and the trap of comparison

There is a reference Vietnamese media return to constantly, and I understand why. In 2026, the Vietnam Olympic team under Park Hang Seo reached the Asian Games semi-finals and finished fourth. It was a historic result, one of Vietnamese football's greatest milestones this century.

But when that result is placed beside this year's squad as a measuring stick for expectation, two different things are being compared.

First, the 2026 cohort was a specially rated generation, assembled from players who had competed together for years at youth levels, with long bonding time, led by a coach with absolute authority in the dressing room. Second, and more important from my vantage point, the 2026 cohort had a far longer preparation cycle, with continuous camps and a deliberately designed friendly programme.

In other words, fourth place in 2026 was not created in two weeks. It was created over years.

When a football nation takes a result built over years and demands it from a squad built in one session, the comparison stops being motivation. It becomes a trap. It puts the coach in the position of defending a standard the same football nation has not yet created the conditions to reach.

People see the glory; I see the silent backs.

The format discrepancy: the numbers do not match, and what that hides

One detail in the pre-tournament report strikes me as more important than it appears: the format is described as fifteen teams in three groups, with the top two from each group advancing to the quarterfinals.

Three groups, two qualifiers each, six teams in total. A quarterfinal bracket needs eight.

Six does not equal eight. This is an internal arithmetic contradiction, and it means one of three things: either additional best-placed third teams advance, or the number of groups and teams is misreported, or the report's phrasing is imprecise.

Why does this matter to a team about to compete? Because it determines how many points are needed to progress. If only two teams per group advance in the narrow sense, every match is a final. If best-placed third teams also advance, a draw carries different value, a defeat may still leave a door open, and the strategic approach to the Uzbekistan match changes entirely.

A coach is not permitted to be vague about format. Knowing how many points are required underpins every decision on rotation, on pushing forward or sitting deep, on spending energy or saving legs for the next match. In a tournament where a team has trained once, any ambiguity about the rules is a doubled risk.

I will track this until the official regulations are confirmed.

The contrarian angle: "one session" is a number being misread

Now I want to go against what most people take from this story.

The popular reading is: one session means the team is weak, means results will be poor, means the quarterfinal target is fantasy. I do not entirely agree, and the reason is not that I am optimistic about the team.

First, "number of collective on-pitch sessions" is not the only measure of preparation. A team may not train together, yet its players are still competing at a high level for their clubs. The six players arriving from the Hanoi versus Song Lam Nghe An match are six players in genuine match condition, quite unlike six who have just spent two weeks doing drills. In terms of ball feel and match rhythm, they may be in a better state than those who assembled early but only played internal friendlies.

Second, a shortage of training time usually pushes a team toward simple solutions. A team cannot install a complex circulation system in one session. But a team absolutely can install a deep defensive block, a back line that holds its distances, a transition plan. Football has seen plenty of underprepared teams go far by simply doing fewer things, but doing them with extreme discipline.

In football, there are umbrellas in the rain that nobody sees; people only see the one standing under them when the rain stops.

Third, and this is the point I want to stress most: the "one session" story may be obscuring a much larger one. It draws the eye to the number of sessions instead of the question: why does a national team have only one session? The answer lies in the domestic calendar structure, in Vietnam's domestic league running in parallel with the national-team window, in both sides having legitimate arguments while neither holds enough authority to impose on the other.

This is a systemic problem. The number of sessions is only a symptom.

The trap of a perfect excuse

I need to say something I consider important, and it comes from the role I have held throughout my career: standing with the weaker party without making excuses for anyone.

These preparation conditions create a shield. If the team fails in the group stage, an explanation is ready: one session, three waves of assembly, six players straight from a domestic match. That shield is real; I have reconstructed it above with the actual facts. But a real shield can still become a reason not to fix anything.

The problem with shields is that they protect a person, but they do not develop a football nation. If this tournament ends in an early exit, and if all that remains is the phrase "the team had no preparation time", then Vietnamese football has lost twice: on the pitch, and in the meeting room.

The reverse is also true and more dangerous. If the team navigates the group stage spectacularly, voices will argue that limited preparation is not a problem, that youth football only needs spirit. That is a false conclusion drawn from far too small a sample. One lucky case does not refute a rule.

I am old now, which is why I have the patience to wait for a season to mature. But I am also old enough to know that patience is not the same as silence.

Real people, and responsibility that cannot be pinned on one individual

One principle I set for myself when I began writing at The Independent in 2026 is never to point at an individual when a system fails.

In this story, the easiest person to point at is head coach Đinh Hồng Vinh. He received a squad assembled in three waves, trained once, then entered a tournament with a quarterfinal target announced at federation level. If the team loses, his name is called first.

But responsibility here is diffuse. Who decided the domestic fixture calendar? Who decided the national-team window? Who decided clubs could hold players until the last matchday? Who decided to publish a quarterfinal target while knowing the preparation fund? None of those answers leads to a single name. That is precisely why turning this into a story about one coach is the easy and the wrong reading.

What I want to see are the other backs. The team doctor, who must judge how much load the six players straight from a domestic match can carry. The fitness specialist, who must design a recovery programme compressed into two days. The logistics staff, handling the overnight flight, the first meal in a strange country, the sleep of twenty-three players in a new time zone.

Every contract is a layer of sediment; others read the value, I read the past.

In this case, the sediment layer I want to read is how Vietnamese football handles the relationship between clubs and the national team. It is a question many Southeast Asian football nations face, and it has no answer within a single season.

Scenarios and probabilities: three paths for Vietnam U23

When analysing cases like this, I always build three scenarios to remind myself that outcomes are not a straight line.

The first, the optimistic one: the team keeps a clean sheet in the first half against Kuwait, converts a set piece to win or draw, then beats the Philippines and enters the Uzbekistan match relaxed. Whether this happens depends considerably on whether the back line holds for the opening thirty minutes. A defensive block that has not trained much tends to break early, when distances are loose and players cannot yet read each other.

The second, the neutral one: the team draws with Kuwait, beats the Philippines, and the Uzbekistan match decides first or second place. This is the likeliest scenario if we assume Vietnam's U23 player quality is enough to get past the Philippines but not enough to dominate the two sides above them.

The third, the negative one: the team either loses to Kuwait or drops unexpected points against the Philippines, and the Uzbekistan match becomes an early final. This is the scenario an underprepared team is most likely to fall into, because it originates in small errors in the first match.

What I want to stress is that all three scenarios circle a single variable: the ability to hold organisation in the first half of the opener. If that variable is healthy, everything behind it opens up. If not, the whole tournament is forced into catch-up mode.

What to watch before 15 September

With a preparation problem like this, there are specific indicators I will note in my book over the next two days, rather than waiting for results.

The first is the official squad list for the Kuwait match. If the two latest arrivals are absent from the starting eleven, it signals the coaching staff do not trust their rhythm. If they start, it signals the team lacks options and is forced to gamble.

The second is how many Song Lam Nghe An and Hanoi players start. This is the group with the highest load and also the best match feel. How the staff balance those two extremes will reveal how they read the situation.

The third is the defensive structure in the opening twenty minutes. Not the result, but the distances between the lines, and whether the midfield can seal the space in front of the defence.

The fourth is the official group-stage format. Until it is confirmed, I maintain my assessment that progression maths for Group C cannot be determined with certainty.

What remains after all of it

I have been through many youth tournaments. I have sat in near-empty stands, recording players nobody remembers ten years later. I have seen talents forgotten because of an injury, a wrong transfer, a decision made by adults when they were seventeen.

So when I look at a U23 team assembled in three waves and trained once, I do not see farce or tragedy. I see a group of young people placed in circumstances they did not create, and asked to overcome them.

Under the city dust, I still find gems nobody has had time to see.

What I hope for is not a beautiful result. What I hope for is that after this tournament, the debate in Vietnam does not stop at the number of sessions. It will go further, to the question of what a football nation must pay at the calendar level if it wants to achieve something at continental level.

One session does not decide a tournament. But how people explain one session can decide the next ten years of a generation.
