Five Days and Two Voids: Kim Sang Sik's Unchanged Choice

The training ground echoed with nothing but the sound of the ball. Five days. Not five weeks, not five months. Just five days before Vietnam's opening match of the FIFA ASEAN Cup 2026 against the Philippines on Indonesian soil, and in that brief window, head coach Kim Sang Sik did something part of the fanbase did not want to hear: he kept the old core intact.

I have sat through enough short camps in nearly four decades of this work to know that five days do not create a new team. They only allow a group to remember who it already is. Between the two whistles, there is a world the scoreboard can never measure. That world lives in passes a player makes without looking, in the way a midfielder turns his back to shield the ball under pressure, in the rhythm that only those who have played together long enough could understand.

Kim Sang Sik understands this. But what he faces is not only a philosophy question. It is a brutal equation of time, personnel and expectation.

Context: A title and two voids

Vietnam enter the tournament as defending ASEAN Cup champions. That label sounds grand, but it is also a tightening rope. Fans no longer want to see their team scrape through; they want to see a Vietnam that plays differently, with sharper definition. The South Korean coach himself spoke of finding new options and refreshing the playing style. But the tournament does not give him the time to do so.

And as if time were not cruel enough, the two most important names face the risk of missing out. Nguyen Hoang Duc — the tempo-setter, the press-breaker, the playmaker — is unlikely to recover in time. Nguyen Van Vi — the two-way left-back, a pillar of the defensive line — is in the same situation. Two positions, two functions, lost at once.

This is not a simple personnel loss. This is the loss of an entire system.

Core: When familiarity becomes a shield

Looking at the squad list, one consistent logic emerges: prioritizing players who already understand Kim Sang Sik's system. They do not need to relearn movement patterns; they do not need to reacquaint themselves with tactical demands. They just step in and play. In a short tournament, that is a defensible choice — even a wise one.

But it also sets a clear ceiling. Familiarity keeps a team running smoothly, yet it does not create surprise. And in modern football, the side that can be read is the side that can be neutralized.

Hoang Duc's absence is the hardest piece to replace. He is not merely a midfielder; he is the entire team's pressure valve. With the ball, he sets the tempo. When surrounded, he finds the escape route. When the team sinks, he pulls the rhythm back up. Without him, Vietnam will most likely shift toward a more direct game, more long balls — meaning a loss of control against opponents who know how to sit in a compact block.

The left flank is no different. Van Vi is the kind of full-back who defends and attacks, generating overlapping pressure. In his absence, Cao Quang Vinh — a Hanoi Police FC player — emerges as the alternative. But he is a different dimension, not a replica of Van Vi. That means the way the left side operates will change, not just the name on the team sheet.

The return of Nguyen Filip also matters. As Hanoi Police FC's goalkeeper, he brings healthy competition. But competition at the goalkeeper position always has two sides: it raises the standard, yet it can also create instability if not settled decisively before the tournament.

Another notable point is the naturalization route. Adou Minh and Kyle Colonna (Luong Chi Khai) have recently obtained Vietnamese citizenship. This is a depth-building channel that costs no transfer fee, an economical yet sustainable way to build a squad. If it succeeds and proves compliant, the model could become a long-term talent pipeline for Vietnamese football.

Contrarian angle: Familiarity has its own price

What is discussed less is the flip side of stability. The more you keep the core intact, the more your team becomes an easy target to predict. Vietnam's opponents can study the old playing style carefully and prepare ways to stop it. Familiarity helps insiders understand each other, but it also teaches outsiders how to read the playbook.

There is another paradox: Kim Sang Sik has publicly spoken of finding new options, but the short format of the tournament prevents him from doing so. He is trapped in a transition trap: committed to renewal, yet never given enough time to deliver it. The result is that renewal keeps being postponed, and the team grows ever more dependent on an aging core.

I recall a story. In 2026, at the World Cup in Russia, I mispronounced a player's name three times. I spent 47 days correcting it. Fixing a wrong name takes 47 days; keeping a person's trust takes forever. A team is the same — lose a rhythm, a person, a trust, and it may take a great deal of time to repair. Nothing returns to normal on its own.

One more thing: the FIFA ASEAN Cup 2026 is hosted by Indonesia. Vietnam will be the visiting side, playing in a stadium full of noise and resistance from the stands. In that environment, set pieces and composure under crowd pressure may matter more than intricate play. The emptiest stadium still has a breath, but a packed one can still stifle the breath of a squad forced to travel far from home.

What is worth waiting for

It is no coincidence that many fans want to see Vietnam play differently after the title. The pressure is not about whether they win, but how they win. That is a new standard, higher and harder.

What Vietnam truly need now is not a tactical revolution, but lucidity in how they use their people. The two voids must be filled with solutions, not hope. The fans' faith, however great, cannot replace a rhythm calculated at the right moment.

As for Kim Sang Sik, perhaps he understands best that time is the most expensive commodity. Football never owes us a result; it only owes us a story. And we are about to hear that story — starting with a match on Indonesian soil, with a team keeping its old core, and a heart beating fast on the edge of the pitch.
