ASEAN Cup 2026 Champions: Attack Shines, But Vietnam's Defense Still Has 'Worries' Ahead of the 2027 Asian Cup

Bangkok night, Rajamangala Stadium was ablaze in a sea of red flags with yellow stars. As the final whistle blew, the Vietnamese players embraced in sheer ecstasy. The 2026 ASEAN Cup title had come home, the third in our history, and the second consecutive under coach Kim Sang Sik. But amidst the jubilant atmosphere, I recalled an afternoon reading contracts in Kazan in 2026, when I was too hasty in concluding the future of Takashi Inui. The lesson from that year taught me one thing: never let the celebration cloud the flaws simmering beneath. And for the Vietnam national team right now, those flaws are very evident. Look at the numbers. In 8 matches at the 2026 ASEAN Cup, Vietnam conceded only 3 goals, keeping 6 clean sheets. Compared to the 2026 campaign when we conceded 6 goals, this is a clear statistical improvement. But as I often tell young colleagues: "In the transfer market, a release clause is never just a number — it's a declaration of war." Here, the 3-goal figure does not reflect the true state of the defense. It was propped up by too many fortunate factors: opponents squandering gilt-edged chances, woodwork interventions, and especially the outstanding performances of goalkeeper Patrik Le Giang. I watched every Vietnam match in this tournament, and what concerned me most was not the results, but how we operated. Our defense frequently fell into a passive state, exposing deadly gaps in the central channel. Without Patrik Le Giang's incredible reflex saves, the story could have been completely different. This is the point I want to emphasize: over-reliance on a single individual in the goalkeeper position is a gamble. If Le Giang's form dips, or worse, he suffers an injury, our already fragile defense will be fully exposed. Another systemic issue I noticed is the slow start in the first half. In almost every match, Vietnam entered the game cautiously, even passively, and only truly found their rhythm after the break or following tactical adjustments from coach Kim Sang Sik. This is not a deliberate tactical approach, but rather a reflection of the team's limited ability to impose their style of play from the outset. This pattern has repeated since the 2026 ASEAN Cup, indicating it's a structural problem, not a one-off incident. Coach Kim's in-game adjustment capability is a genuine strength, but this reactive style will become extremely dangerous against higher-caliber opponents who can punish early mistakes and control the game's tempo. The two goals conceded in the final against Thailand are a wake-up call. Before that, from the group stage to the semifinals, we had conceded only 1 goal in the 3-1 win over Cambodia. So, the remaining 2 goals all came in the final match, against the strongest opponent in the tournament. This shows that when facing a team with good attacking quality, our defense becomes more fragile than ever. This is a worrying signal ahead of the 2027 Asian Cup, where every opponent in the group will be of comparable or higher quality than Thailand. Coach Kim Sang Sik himself acknowledged this. In his post-final interview, he said: "The defense needs more preparation. We need to improve our ability to withstand great pressure." The admission of an experienced coach is a significant signal. He is not intoxicated by the victory but is seeing the problems that fans might overlook in the joy of winning. This is a wise expectation-management strategy, both to lower public expectations before the Asian Cup and as a subtle message to the Vietnam Football Federation (VFF) that the team needs more resources and preparation time. Looking ahead to the 2027 Asian Cup, the context will be completely different. Opponents like South Korea, the UAE, or even Yemen, are not as forgiving as Southeast Asian teams. They have superior physical, technical, and tactical foundations. They will not miss the gilt-edged chances like our ASEAN opponents did. They will not give us time to find our rhythm after the break. If we maintain the same reactive style and reliance on the goalkeeper, an undesirable outcome is entirely possible. I still remember my words after the COVID summer of 2026: "The COVID summer taught me one thing: whoever reads the contract carefully knows how to breathe." Now, I want to tell you: whoever sees the problems after a victory truly understands football. The 2026 ASEAN Cup title is a brilliant success, a testament to the progress of Vietnamese football. But it is not the final destination. It is just a milestone on a long road, and ahead lie much greater challenges. The question now is not whether we deserve the championship, but whether we are sober enough to recognize our problems and fix them before entering a much harsher arena. Because, as I have said many times: "Cups are lifted in May, but decided on winter afternoons reading contracts." For the Vietnam national team, those afternoons of preparation for the 2027 Asian Cup are drawing very near, and that is when the truth will truly be revealed.
