Vietnam and the Rhythm Problem Before the FIFA ASEAN Cup Opener

An Afternoon at the Training Ground

Three in the afternoon, the sun stood still on the grass. Vietnam's players split into two groups, and what I wrote in my notebook was not any shot but the distance between the two lines each time the ball changed direction. An assistant coach stood at the centre of the pitch, arms spread wide as if trying to pull the whole team into a single frame. He held that pose through three blocks of the session, and I noticed the centre-backs kept glancing sideways far more than they looked at the ball.

I have sat at many training grounds: the corner of Camp des Loges in 2026 when Neymar and Mbappé had just arrived in Paris, those June 2026 evenings in Kazan when Benjamin Pavard stayed behind heading balls until nine o'clock, and before that the sports desk at Belgrade Television in 2026. At 68 I still keep the habit of arriving forty minutes before the session. A training ground never lies. It only whispers to those willing to stay behind.

That is why I left that session with a question that had nothing to do with goals.

Favourites, and the Signals of an Early Morning

Vietnam enter the FIFA ASEAN Cup as the leading candidate in Southeast Asian football. Coach Kim Sang-sik has stated his team will play more attacking football without losing its defensive foundation. The opponent on the September 26 opener is the Philippines under coach Cuadrat. It was Cuadrat who produced the most interesting pre-match line: he placed Vietnam among the title contenders and cited a gap of roughly forty places in the FIFA ranking between the two teams. September 29, against Thailand, is the real test at the same tier.

But the personnel picture is not as flat as the ranking.

Vietnam's biggest problem across this cycle appeared in the same place session after session: the ability to hold shape after losing the ball. The squad assembled late, with many players having just finished a heavy domestic season. Hoang Duc retains the captain's armband but is not certain to play. Thanh Chung is injured, opening a replacement slot for Ngo Dang Khoa. The list is therefore both short of bodies and forced to reorder its priorities after a single injury.

Cuadrat said Philippine football will not use missing players as an excuse. He also said his side will play on equal terms. I noted both sentences and underlined the second.

A Principle of Space, Not a Formation

What Kim Sang-sik means by keeping "all eleven players in one frame" is not about a formation. It is a principle of occupying space. The team does not need to ask whether it plays 4-3-3 or 4-2-3-1; the question is whether, when the ball is lost, the two lines are still less than fifteen metres apart.

Vietnam's entire tactical ambition sits in the distance between midfield and defence in the first three seconds after losing the ball — not in the number of goals scored.

Kim's dual statement — more attack while retaining defence — is a familiar form of risk management. He wants a higher defensive line and more possession against the Philippines, but he does not want to expose a back line whose key figures are not physically guaranteed. That requires the team to compensate with running rhythm, and running rhythm is precisely what is scarcest in this period.

Cuadrat said he has shown his players video of Vietnam's naturalised players. That suggests the Philippines will sit in a low block and target the transition moment. This is the most awkward opponent type for a team wanting to play high: they do not need the ball, they need one error.

Based on my experience of watching matches, three signals are worth watching in the first half on September 26.

First, the first pass from centre-back into midfield. If it travels sideways more than forward, Vietnam are hesitating.

Second, the position of the two full-backs when the ball is on the opposite flank. If they do not tuck inside, the block will tear horizontally, exactly where the Philippines want it.

Third, the reaction after the first lost ball. A team that knows its fitness is short often reacts slowly in that exact moment, and not because it fails to understand the plan.

Kim's captaincy structure also deserves close reading. One captain whose availability is in doubt, two vice-captains in Xuan Son and Dinh Bac. That is a deliberate generational handover. Dinh Bac was born in 2026, won the V-League, was listed by FIFA as a player to watch, and now carries added responsibility. Kim said the vice-captaincy will bring him greater responsibility. This is a way of applying developmental pressure, not a ceremony.

But that design is thin. If Hoang Duc does not play, the leadership load falls to a twenty-two-year-old in his first senior leadership role.

Ngo Dang Khoa is another pathway. Born and raised in Western Australia, he came to the V-League, obtained Vietnamese citizenship in May, and entered the squad only because Thanh Chung was injured. This is a low-cost talent-acquisition channel, and it is repeatable. But Khoa's value at senior international level is unproven: he has a meniscus injury history, and this call-up reads as an investment in potential rather than verified output.

When Being Highly Rated Becomes a Burden

From outside, Vietnam's situation is read with one word: easy. A group containing the Philippines, a large ranking gap, the region's number one contender. That reading ignores the pressure mechanism it creates.

When a team is labelled the number one contender, every result short of a win counts as failure. A draw in the opening round stops being a point; it becomes a debate about selection. And that debate will aim at exactly where Kim is taking his biggest risk: the fitness of his key players.

Cuadrat understands this. When he says Vietnam are contenders, he is transferring pressure to the other side. When he says the Philippines will play on equal terms, he is announcing his team will not park the bus. Placed together, those two sentences form a plan: sit deep, wait for an error, and let expectation do the rest.

There is a further layer rarely mentioned. The previous ASEAN Cup was staged outside a FIFA window, so clubs were not obliged to release players. Vietnam benefited indirectly: because most of its key men play domestically, the team had full availability and camp time, while the Philippines had to field a younger squad. Cuadrat refuses to use this as an excuse. Such a refusal is often a way of registering an injustice without filing a formal complaint.

And if this year's tournament is organised with FIFA as a formal partner, window enforcement and eligibility conditions may tighten. That structural advantage does not renew itself automatically.

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

My point is not that Vietnam are weak. They are stronger than the Philippines in squad quality, and the ranking gap is real. But the greatest risk for a highly rated team does not lie with the opponent. It lies in the possibility that the team is forced to drop its tempo — quietly, unnamed, until the scoreboard speaks for it.

Russia was strangely silent. And that silence said the most. I learned it in Kazan: a team with a fitness problem will not shout. It simply passes more safely, runs half a metre less per phase, and lets the match drift.

The second blind spot is Dinh Bac. FIFA put him on its players-to-watch list, he has just been decorated, and he has become a vice-captain. The more acclaim, the steeper the way back. If he is quiet in the first two games, the story will invert faster than the speed at which it was built.

What to Track

The thing worth tracking is not the score on September 26. It is the tempo in the first twenty minutes: will Vietnam press high, or accept a lower block to save legs for September 29 against Thailand? If Kim chooses the latter, it is a correct decision on fitness and a gamble on psychology, because it runs against his own words about a more attacking team.

One beat does not make a piece of music. One match does not make a football life. But the opening beat usually decides the tone of the whole tournament.
