Champions but not perfect: The knots Vietnam must untie before Asian Cup 2027

The dawn of Ulsan never lies, but the dawn at My Dinh Stadium after the ASEAN Cup coronation night carries a different hue. Fans erupted in joy, flares lit up the sky, and on the stands, red flags with yellow stars fluttered in the wind. But I, at 61, standing amidst that fervent crowd, remembered a phone call at 4 AM from Ulsan years ago. There are phone calls that last only three minutes, but they change an entire summer. And there are championships that, once the joy subsides, reveal cracks not everyone is sober enough to see. Let's talk about the numbers first. In eight matches at the 2026 ASEAN Cup, Vietnam conceded only 3 goals and kept 6 clean sheets. Compared to the 2026 campaign when they conceded 6 goals, this is a 50% statistical improvement. But fans see a contract; I see the sleepless nights behind it. Because, as the analysis pointed out, Vietnam's defense 'often looked surprisingly vulnerable despite conceding few goals.' Patrik Le Giang's miraculous saves, shots hitting the woodwork, opponents inexplicably missing golden chances – all of this masks the reality that the defensive process is not as solid as the results suggest. More worrying is a pattern that has repeated since 2026: Vietnam almost always starts slowly in the first half, only finding rhythm after the break or after Kim Sang Sik's tactical adjustments. This is not an isolated incident but a structural characteristic of the team. It reflects a limited ability to impose their style of play from the outset. And if ASEAN opponents can forgive this sluggishness, then at the 2027 Asian Cup, where opponents like South Korea, UAE, or Yemen never show mercy, this will be a fatal weakness. The two goals conceded in the final are a notable wake-up call. From the group stage to the semifinals, Vietnam conceded only once, in a 3-1 win over Cambodia. So where did the other two goals come from? From the final, where the tournament's strongest opponent successfully exploited the spaces left by Vietnam's defense. This shows that when facing higher quality attacks, our defensive system becomes much more fragile than its sturdy appearance against weaker teams suggests. This is an alarming signal ahead of the Asian Cup, where every group-stage opponent is of comparable or higher quality. The only bright spot, and also Vietnam's biggest pillar right now, is Kim Sang Sik's ability to adjust during halftime. The team's consistent second-half improvement demonstrates his in-game management and tactical flexibility are real. But this reactive approach will not be sustainable against opponents who can punish early mistakes and control the game's tempo. They won't give Vietnam the chance to correct mistakes after the break. Son Heung-min was stoned in 2026, and I learned to see people not through public opinion. Likewise, I look at Patrik Le Giang and see an excellent goalkeeper, but I also see a dangerous dependency. If his form dips, or worse, he gets injured, will Vietnam's defense be completely exposed? Le Giang's saves are inadvertently masking structural holes. And modern football runs on money, but the call at dawn runs on trust. The trust here is honesty in assessment, not sophistry for a beautiful result. The story of the 2026 ASEAN Cup triumph is a beautiful one, but it should not obscure the problems that coach Kim Sang Sik himself has acknowledged. He said the defense needs more preparation, and the first half is an issue. That is a strategic admission, a way to lower expectations before the Asian Cup while signaling to the Vietnam Football Federation about the need for more investment. But whatever the reason, the truth stands: Vietnam is regional champion, but there are still knots to untie before stepping onto the continental stage. The empty summer of 2026, Kim Min-jae canceled his contract, and football stood still for us to reflect. Now, there is no stillness for Vietnam. The 2027 Asian Cup is approaching, and questions about the first half, the dependence on the goalkeeper, the ability to withstand pressure from stronger opponents – all need answers. The ASEAN Cup title is a milestone, but it is not the destination. It is just a stop on a long road, where those who are truly serious about Vietnamese football will not sleep on victory, but will wake up, as I still wake up at 4 AM, to find answers to the problems that the joy of victory is trying to hide.
