2026 ASEAN Cup Champions: Why the Triumph Still Leaves Unanswered Questions?

In Bangkok night, the final whistle echoed, and millions of Vietnamese hearts burst with joy. We did it, successfully defended the Southeast Asian throne. But amidst the festive atmosphere, professionals like me have an indescribable feeling. Looking back at the 8-match journey, the numbers of 3 goals conceded and 6 clean sheets are respectable achievements. However, the football we displayed, especially in the first half of matches, is raising big questions that perhaps the answers must come from the challenging 2027 Asian Cup ahead. The journey at the 2026 ASEAN Cup under coach Kim Sang Sik began with an astonishing solidity in defense. From the group stage to before the final, we had only picked the ball out of the net once, in the 3-1 win over Cambodia. That is a significant improvement compared to the 6 goals conceded in the 2026 edition, a 50% reduction. But looking closely at the flow of each match, it becomes clear that this solidity came from factors of luck and individual brilliance rather than a truly well-oiled defensive system. Opponents missed golden chances, the ball found the woodwork, and above all, there was the outstanding performance of goalkeeper Patrik Le Giang. These elements inadvertently masked tactical holes that, against stronger opponents, things could have been different. I followed the team's matches very closely in this tournament and noticed a systemic pattern: Vietnam almost always starts matches slowly and without ideas. We usually only find our rhythm and sharpness after the halftime break or following tactical adjustments by coach Kim Sang Sik. This is not a deliberate tactical approach but rather reflects a limited ability to impose our style of play from the outset. This has been repeating since the 2026 ASEAN Cup, indicating this is a structural issue rather than a random one. The sluggishness in the first half puts unnecessary pressure on the team, and if opponents capitalize better, the story could have been completely different. The most worrying point is the two goals conceded in the final. If the defense had only conceded once before, then conceding twice against the tournament's strongest opponent is a thought-provoking signal. It shows our defensive system has specific vulnerabilities when facing high-quality attacking transitions or set-piece situations. These are exactly what South Korea, UAE, or even Yemen will exploit mercilessly at the 2027 Asian Cup. The level of teams at the Asian Cup is a completely different class compared to regional opponents. They will not miss the chances that Southeast Asian teams have missed against us. Coach Kim Sang Sik's ability to adjust during halftime is a genuine strength. The team consistently playing better in the second half demonstrates his acumen and ability to turn the tide. However, this reactive style will become extremely dangerous against opponents capable of punishing early mistakes and controlling game tempo. They will not give us time to correct errors, and once behind, coming back against tight Asian defenses will be a nearly impossible task. The reliance on goalkeeper Patrik Le Giang is also a question mark. His outstanding performances earned crucial points, but if his form dips or he unfortunately suffers an injury, the already fragile defense could crumble. We are placing too much faith in an individual rather than a system. And then, although the championship is a great success, it also inadvertently places immense pressure on the whole team. Fans will have the right to expect a successful Asian Cup campaign, but if we are eliminated in the group stage, would that be a regression? I think the answer is no, as the level of the continental tournament is a completely different story. The match against South Korea, coach Kim Sang Sik's homeland, will be a particularly significant test. It will be an emotional match, creating invisible pressure on the Korean strategist. He himself has admitted the defense needs better preparation. That admission shows this coach has a very realistic view of his team's true strength. Ahead, improving first-half entry into the game and reinforcing defensive solidity against opponents with superior speed and technique are two key tasks. The preparation time before the 2027 Asian Cup is a valuable opportunity for him to build a more proactive style of play, rather than just reacting after the break. The Asian pitches will wait for no one. The Southeast Asian championship is a proud milestone, but it is only a stepping stone on the long road ahead. Vietnamese football needs to look beyond the glory of regional cups, towards a bigger arena, where harder problems await solutions.
