Vietnam stick with familiar core for FIFA ASEAN Cup: Safety or a forced move?

The dawn in Ulsan never lies, but the dawn in Busan this morning carries a different weight. When I opened my phone, a message from an old friend at the Vietnam Football Federation read simply: 'He's keeping the same core. We're about to see another summer without experimentation.' I sat back, poured a cup of coffee, and thought about the 4 a.m. call I received from Ulsan in 2026 – how a seemingly safe decision can change an entire season. Head coach Kim Sang Sik has just announced his squad for the FIFA ASEAN Cup 2026, and as expected, he has made almost no changes from the lineup that helped Vietnam win the regional title before. Instead of welcoming new faces, the South Korean tactician continues to place his trust in the pillars who have absorbed his philosophy. But the story doesn't stop at 'keeping the squad.' It lies in the context behind it: only five days of preparation before the opening match against the Philippines, two key players – Nguyen Hoang Duc and Nguyen Van Vi – almost certainly missing through injury, and the tournament taking place on Indonesian soil, where crowd pressure will be a significant challenge. There are phone calls that last only three minutes but change an entire summer. Kim Sang Sik's decision to keep the old core is not tactical laziness but a survival calculation in a context of scarce time. With five days of training, no coach in the world can build a new playing identity. What he can do is reinforce mutual understanding among players already familiar with each other's movements. This is a low-variance choice, but it also caps the team's tactical ceiling. The absence of Hoang Duc is the heaviest blow to Vietnam's ambition to control matches. In Kim's system, Hoang Duc is not just a central midfielder; he is the pressure-release valve, the tempo-setter, the bridge between defense and attack. Without him, Vietnam will be forced into a more direct, faster, and more long-ball-dependent style – a change in identity, not just position. Similarly, Van Vi's absence weakens the left-side attacking channel, where he often pushed high to create space. Cao Quang Vinh, expected to replace him, brings a 'different dimension' – but that is a change in player profile, not a like-for-like swap. I remember the 2026 World Cup, when Son Heung-min was criticized for not scoring despite running 11.2 km in a match. I learned that public opinion often looks at results, not process. For Vietnam, the previous ASEAN Cup title has created high expectations, but the 'unconvincing displays' recently are a sign that results are outrunning substance. This is a dangerous signal: if Vietnam starts slowly in Indonesia, criticism will not only target results but also the 'conservative' approach of coach Kim. The blind spot in this official narrative is the stalled generational transition. Kim Sang Sik once publicly stated his desire to find new options, but the tournament format does not allow experimentation. The result is a vicious cycle: he cannot rejuvenate because of time constraints, and because he cannot rejuvenate, he becomes more dependent on an aging core. The return of naturalized players like Adou Minh and Kyle Colonna provides a supplement, but it does not solve the root problem: an aging squad without a real succession plan. At 61, I still pick up the phone at 4 a.m. – because Ulsan doesn't call to say goodnight. For Vietnam, the question is not whether they can retain the crown, but whether they can escape their own trap: a familiar core, a predictable style, and a fan expectation that they will 'play differently.' Without a tactical breakthrough or a surprise factor, the journey in Indonesia may well be a test not only of nerve but of the ability of a collective standing at its own crossroads to adapt.
