Vietnam face squad concerns ahead of FIFA ASEAN Cup: Van Vi, Hoang Duc and Duy Manh attract Indonesia’s attention

Indonesian media are paying special attention to Vietnam’s squad list ahead of FIFA ASEAN Cup. According to newly published regional football articles, Van Vi, Hoang Duc and Duy Manh all appearing on the injury watch list has become a hot topic. But someone who has spent years with data would see absence only as the visible part. Data do not lie, but they know how to hide inside the standard deviation. The context goes beyond a single training session. Vietnam enters the regional tournament with a familiar spine, in which coach Kim Sang-sik relies on wide speed and central midfield consolidation. Van Vi is a left-sided defender who pushes high, supports attacks and often receives the ball between the opponent’s full-back and centre-back. He once opened the scoring in Vietnam’s 3–0 win over Indonesia. If he cannot recover in time, Vietnam would not simply lose a fast runner; they would lose an established pressure-relief valve used dozens of times per match. Hoang Duc’s role is different. He does not need to cover the most ground, but he is the player in front of defence who shifts the direction of attack. In that same 3–0 win over Indonesia, he recorded two assists. That shows his value lies in line-breaking passes under pressure, not in metres covered. Duy Manh, perhaps less discussed than his two team-mates, remains an anchor in defence due to his command of the back line and his aerial presence. From a tactical perspective, the problem is not one injured player but two attacking pathways being questioned. Kim Sang-sik’s system often uses a deep centre-back to pull the ball to the left wing; Van Vi is the one who accelerates from that position. If the staff are forced to use another option, the team can fall into sideways circulation around the central area, exactly what a deep Southeast Asian defence is comfortable dealing with. Indonesian media may have seen that. Several articles express optimism because they believe Vietnam losing three core players at the same time before a tournament is too heavy. In the moment they mention Indonesia taking advantage of defensive errors, they unintentionally underrate Vietnam’s next layer of squad depth. It is not fair to say Indonesia are wrong. Exploiting an opponent’s weakness is natural for an ambitious football nation. However, a national team needs more than an absence list to win. From the ashes of World Cup 2026, I learned that Russians read football through desperate memory. When a team is pushed into a difficult situation, sides with cultural depth and discipline often find a different emotional state, one that cannot be measured by training data or fitness tests. Head-to-head history supports that view. Vietnam have often played without the most highly rated players yet kept their cohesion through positional rotation. If Indonesia focus solely on attacking the left flank where Van Vi is missing, they may forget Vietnam still have younger full-backs capable of performing a different tactical task. Inside the dressing room, what Kim Sang-sik needs now is not an immediate answer over who replaces whom. The transfer window is not a battle of money; it is a battle of those who know how to wait. A national team does not become champions by keeping the expected squad intact. It becomes champions when less famous players understand how to occupy the space left by stars. No data suggest Indonesia will play better simply because Vietnam are missing players. The only change is the deviation from the planned script. If Indonesia attack heavily down the left, they will meet a centre-back more likely to narrow centrally. If they press Hoang Duc, they will have to sacrifice a body in midfield and create space for other attacking midfielders. The coming match, should early reports be confirmed, will be a test of Vietnam’s bench quality. Duy Manh’s recovery is still unclear. Van Vi may receive intensive treatment. But the real issue is how the coaching staff turn imperfect conditions into a new pathway. Indonesian media may feel energised. They are entitled to hope. Yet when a team starts believing victory will come from the opponent’s medical room, they often forget that the ball will still roll on grass with their own football. FIFA ASEAN Cup has not started, but it has entered a noisy zone. Those who see the match only on paper will be surprised. Those who read the damage inside the squad will see a different message: every absence list is only valid until the referee blows the whistle.
