Vietnam Keep the Familiar Core for the FIFA ASEAN Cup 2026: The Five-Day Gamble

On the first day of camp, Kim Sang Sik stood in the middle of the pitch with a tactics board in his hand. He did not open with a new formation. He called out the names of players who already understood each other across several tournaments, men who know each other's movement rhythms so well that a glance is enough. No trial session was scheduled. No group of players was split off to audition. Five days. And in five days, no coach can teach a footballing idea from scratch.

When the pitch falls silent of shouting, that is when we hear football sigh. This time the sigh came from the calendar.

The FIFA ASEAN Cup 2026 kicks off in Indonesia in late September, and Vietnam enter as regional title holders, opening against the Philippines. Away team, away ground, a crowd leaning firmly toward the host. That setting forces any coaching staff to rework the personnel equation before they even reach the tactical one.

The squad list reveals a clear choice: keep the familiar core. The names most discussed are not new faces but returning ones. Nguyen Filip and Cao Quang Vinh, both on the books of Hanoi Police FC, are expected to join up. The overseas-Vietnamese group, Adou Minh and Kyle Colonna (Luong Chi Khai), have just completed the process of obtaining Vietnamese citizenship, opening a reinforcement channel that has never been exploited at a systemic level.

In the other direction, two pillars are likely to miss out through injury: Nguyen Hoang Duc and Nguyen Van Vi. Hoang Duc is the tempo-setter, the man who beats the press, the organiser of play. Van Vi is the two-way link on the left flank, attacking and defending at the same rhythm. Losing both at once does not mean losing two positions; it means losing two functions.

Kim Sang Sik has spoken of finding new options. He has also led the national team through a two-year cycle and was retained after the most recent tournament. But five days do not allow anyone to be stable and experimental at the same time. That is where any analysis must begin, and it is also the limit of any criticism.

Keeping the familiar core is not a lazy decision. It is the choice of someone who has weighed the cost of disruption. In a short tournament, mutual understanding is an asset that cannot be bought with transfer money. A centre-back who knows where his partner will drop before the ball is played; a midfielder who knows when to slow the tempo; a full-back who knows when his teammate needs cover. Those things come only from time spent playing together.

The heart of this choice is trading tactical ceiling for stability — the team buys its ticket to the knockout rounds with familiarity, and pays for it with the ability to surprise.

The tactical consequence of Hoang Duc's absence is predictable. Without a press-resistant player in midfield, a team tends to go more direct: fewer short passes near the opponent's box, more long balls, more rapid transitions. That approach survives against opponents who open up, but withers against a deep, well-organised block. Without Hoang Duc, Vietnam has almost no option for keeping the ball when pinned back.

The left flank is the second story. Cao Quang Vinh is seen as the replacement for Van Vi, but the coaching staff themselves describe him as a “different dimension”. That is the polite way of stating something simple: the same position does not mean the same role. Modern football is homogenising wingers by inverting them, turning the flank into a place where the full-back copes alone. Traditional touchline players are dismissed as outdated, when their value lies in stretching the pitch — the thing every organised defence fears most. Van Vi belongs to that mould.

Nguyen Filip's return in goal creates healthy competition, but it is also a variable that must be settled early. The goalkeeping position cannot tolerate ambiguity stretching across the group stage; the defence in front needs to know who is behind them before it dares to push up.

The overseas-Vietnamese channel is a structural bright spot. Adou Minh and Kyle Colonna represent a way of deepening defensive options at far lower cost than buying players on the transfer market, while not occupying foreign-player slots at club level. The precondition lies in procedure: citizenship is only the entry ticket, and FIFA eligibility is what decides whether they can be registered.

The presence of Hanoi Police FC players in the national squad says something else: a pipeline from club to national team is taking shape. A well-resourced club with quality personnel becomes a stable supply line. Based on my experience watching these matches, national teams built on a cluster of players from one club tend to be more synchronised early in a tournament, because the connections already exist without training.

The worry sits on the other side of that synchronisation. An unchanged core is a fixed reference for opponents. The group stage is short, but the knockout rounds are longer than a coach's memory. The opposition has enough time to review, to identify, to work out who cannot be replaced and who only needs to be isolated.

There is a structural trap here. The coach publicly talks about finding new options, but the tournament format gives him no time to do it. It repeats every cycle: talk of renewal, then keeping the same core, then postponing. Repeated postponement hardens into dependence. That is the consequence of a calendar that does not allow for trial and error, rather than simply a personal failing.

One thing about expectations should be said plainly. Vietnam enter as regional champions, yet those inside the camp admit the recent playing style has not been convincing. This is the classic sign of results outrunning process: the trophy conceals the gaps beneath it. Once the result exists, the public starts demanding the manner. And once the public demands the manner, every draw is read as a defeat.

It is worth remembering that shocks in regional tournaments are rarely miracles. They are the inevitable product of two things: a strong team rotating and underestimating, and a weaker team pressing high without fear. If a side walks out with that attitude, the gap in class on paper flattens within ninety minutes.

Football is not read through the scoreline, but through the heartbeat of the people in the stands. Vietnamese fans have grown used to standing behind this team across many tournaments, and they deserve to watch a side that knows what it is playing.

Writing about football means sitting with people, listening to them describe the match in which they were once themselves. In this team's story there will be someone called up for the first time, someone returning from injury, someone playing a last tournament because age waits for no one. Five days of camp is not enough to write a new footballing philosophy, but it is enough for a group of men to remind each other that they have won together before.

What matters lies ahead. The overseas-Vietnamese channel, the club pipeline, and a generation entering its prime — together those three could produce a different national team, if someone dares to give it time. The question is not whether Vietnam should play differently, but how much the country is willing to pay for a different way of playing.
