Kim Sang-sik's Time Puzzle: Could Vietnam Stumble in the FIFA ASEAN Cup 2026 Opener?

At 10 PM, Noi Bai Airport. A group of players in CAHN jerseys stepped out of the plane, eyes weary from a packed schedule. They had just finished a Champions League Elite match against Osaka on September 15, then played a V-League match against Dong Nai on September 20. Only a few days remain before the Vietnamese national team departs for Indonesia for the FIFA ASEAN Cup 2026. Meanwhile, coach Kim Sang-sik stood at the training ground, looking at his watch, smiling bitterly. He knew that with a nearly full squad, he only had about 5-6 days to experiment, build tactics, and convey his ideas before the match against the Philippines on September 26. This is not an ideal situation, but a nightmare for any coach. The FIFA ASEAN Cup 2026 is a regional tournament with the participation of 10 Southeast Asian teams. Vietnam is the defending champion, having won the previous edition under Kim Sang-sik. At that time, he had longer preparation time, a stable squad, and no pressure from a congested schedule. But this time, everything is different. The CAHN players – key figures like Quang Hai, Dinh Bac, Nguyen Filip, Van Hau, Van Do, Thanh Long, Quang Vinh – all had to fulfill their club duties before joining the national team. CAHN is competing in the AFC Champions League Elite, a continental arena that brings prestige and money but consumes the time and energy of the national team players. CAHN's schedule not only makes things difficult for the national team but also reflects the conflict between club interests and the national team, a chronic problem in Vietnamese football. The truth is that Kim Sang-sik does not have enough time to build a cohesive unit. In theory, he has about two weeks to work with the full squad, but in reality, seven CAHN players only have five or six days. This means that the entire pressing system, attacking combinations, and especially set pieces – elements that require repeated practice – will almost certainly not be polished. I have witnessed many teams fail because of such lack of preparation, and I know that the difference between a team with 2 weeks of training and a team with only 5 days is enormous. Remember ourselves at the 2026 World Cup, when South Korea beat Germany but still got eliminated due to lack of cohesion. That is a lesson I will never forget. But the problem is not just about time. My original article pointed out that the Vietnamese team still has many technical issues to improve after the ASEAN Cup 2026. These issues existed before, and with the lack of time, they will almost certainly not be systematically addressed before the Philippines match. This is a compounding risk: pre-existing deficiencies plus new integration challenges. I don't need to look at xG or PPDA data to know this, because I have followed Vietnamese football long enough to realize that lack of time will ruin any tactical plan, no matter how good it is. Physical conditioning is also a major concern. The CAHN players just went through a series of high-intensity matches: Champions League Elite against Osaka in mid-September, then V-League against Dong Nai in late September. They arrive at the national team in a physical state that is not uniform with those who joined early. Kim Sang-sik wants to apply a high-pressing style, but if the key players are not in top shape, the whole system will collapse. I remember once writing about a Korean team with a similar problem, and the result was that they had to play low, accepting to cede the game to the opponent. That could happen to Vietnam, and that is not what fans expect. But let's flip the problem. Are we being too pessimistic? Could the lack of preparation time inadvertently create a new team, not constrained by old habits? The CAHN players arrive late but they are in high form from continental matches. Quang Hai might be at the peak of his form. The combination of players who have trained long and those who just arrived could create surprises. Moreover, the Philippines is not a very strong team, even though they have their strongest squad. The problem is not time, but the coach's adaptability. Kim Sang-sik has faced pressure before, and he has enough experience to turn the situation around. I remember the shock of the 2026 World Cup in Russia. I was wrong when I predicted South Korea would beat Germany through ball control, but in reality they won through high pressing and a moment of brilliance in the 91st minute. I learned that in football, the only certainty is that I will speak up. And I will say this: Kim Sang-sik may have to simplify the style of play, prioritize solidity over flamboyance. He might choose a starting lineup that has never played together in an official match, with only 2-3 training sessions. That sounds scary, but it could also be an opportunity to create something new, a boldness no one expects. I am not saying Vietnam will lose, but I ask: are we overestimating perfect preparation? Football is a sport of mistakes and adaptation. Kim Sang-sik may have to accept a slow start, but that does not mean failure. Look at the 2026 World Cup, when South Korea beat Germany but still got eliminated. We need to look beyond the opening match. The real question is: can the team improve through each match when time is limited? That is when we will see the true character of the Korean coach. An empty stadium is the most honest mirror football has ever had. When there are no fans, no noise, we see every mistake clearly. And now, when preparation time is short, we will see the true ability of coach Kim Sang-sik. I don't write to be loved, I write to be remembered. And I will remember this tournament as a test of a coach's courage in the face of adversity. Does he have enough guts to turn limitations into advantages? Let's wait and see. The Vietnamese team is facing a challenge bigger than the championship itself. It is a challenge of adaptation, of accepting that not everything is perfect. And as I said, I was wrong at the 2026 World Cup, and that was the best thing that ever happened to me. Because I learned that mistakes are a method, not an apology. Let Kim Sang-sik make mistakes, let him experiment, and let us see if he can turn the impossible into possible. Because in football, as in life, nothing is certain except change. I will watch every match of Vietnam in this tournament, not as a fan, but as someone who has been wrong and is not afraid to admit it. I will look at how Kim Sang-sik manages with a team lacking time, how he uses experienced players like Quang Hai, and how he deals with media pressure. That will be a story worth writing, and I believe it will be no less dramatic than the match itself. Those who hate me read every line I write more carefully than those who love me. And I write this article for both groups: for those who believe Vietnam will win, and for those who are waiting for a collapse. I do not take sides, I only stand for the truth. And the truth is: the Vietnamese team is entering the tournament with a tied hand. But as I said, a tied hand sometimes creates the most creative passes. Let's wait. Finally, I want to emphasize one thing: this tournament is not just a test for Kim Sang-sik, but also a test for the entire Vietnamese football. Can we resolve the conflict between club and national team schedules? Can we create an environment where players can dedicate themselves to both? These are bigger questions than a match against the Philippines. And if we don't answer them, even if we win this tournament, we will still lose in the long run. I have followed Vietnamese football since I was a boy in Hanoi, and I believe we can do better. But that requires change from the roots, not just a victory in one tournament. Goodbye, and remember: data whispers when the whole stadium is screaming. I learned to listen. And now, I am listening to the whispers of fate waiting for the Vietnamese team in Indonesia.
