SEA Games 33 and the courage to forget: Why U22 Vietnam should not copy the senior team's defensive blueprint

On the night of January 5, 2026, at Rajamangala, when the referee's whistle ended the ASEAN Cup 2026 second-leg final, Vietnam's players collapsed onto the pitch like children finding a long-lost toy. I was not in the press area that night. I stood in the stands, among crying supporters, and realized something rarely spoken aloud: that trophy was not just a reward for the past—it was a debt the next generation would pay in unexpected ways. Vietnamese fans are entering SEA Games 33 with the word "invincible" hanging over their heads. U22 Vietnam is expected to replicate the senior team's triumph, as if football were a machine whose formula could be copied from one tournament to another. Yet the very formula that carried Vietnam to the top of Southeast Asia in January could drag us down in the youth arena. I have followed English football for two decades—watching clubs relegated for worshipping a defensive style whose time had passed, and young teams rising because they dared to abandon their inheritance. Sunderland were relegated, and I still maintain: going down is a way of going up—but only if you understand why you went down. The context of 2026 is unlike any other year. Under coach Kim Sang-sik, the national team won the 2026 ASEAN Cup with a clear philosophy: defend in numbers, sacrifice ball possession, wait for transition moments to strike decisively. In key matches, Vietnam accepted less than 45% possession, retreated deep, and relied on sharp counter-attacks from their center-forward. That philosophy worked for the national team for a simple reason: the defense featured Quế Ngọc Hải, Đỗ Duy Mạnh, and Nguyễn Thành Chung—center-backs who had played together for hundreds of matches and read situations like familiar pages. They did not need possession to control a game. U22 Vietnam, however, lacks that kind of experience. At SEA Games 33, we will send to Thailand a generation still short on international experience. Nguyễn Thái Sơn, Khuất Văn Khang, Bùi Vĩ Hào, Nguyễn Quốc Việt—truly talented names, but none has faced the pressure of a final on away soil before 50,000 spectators. If you force them to play reactive defensive football from the start, you do not create a disciplined unit—you create a fearful one. Look at the group-stage data from the 2026 ASEAN Cup. When Vietnam faced weaker opponents and had to take the initiative, Kim Sang-sik's team often struggled to build from the back. Central midfielders lacked escaping options under pressure, full-backs hesitated to dribble, and the ball merely circulated in front of the opponent's box without creating breakthroughs. That was not an individual failure—it was the result of a system trained to react rather than to act. I mispronounced a name three times live on air, but that did not make me wrong with myself. Likewise, a youth team that plays high pressing and concedes three goals in a friendly has not proven its philosophy wrong. Mistakes from the past are data, not sentences. Yet many young coaches in V-League and national youth teams remain obsessed with safety and immediate results, teaching players how not to lose before teaching them how to win. Youth football is not the same as elite football. At ages 20-22, players must be tested in high-pressure environments; they must make mistakes to understand their limits. A young center-back who only clears the ball under pressure will never learn to escape a press with a short pass between the opponent's midfield lines. A striker who only makes runs for counter-attacks will never develop the ability to hold the ball with his back to goal and maneuver in tight spaces—something modern football demands of every position. I recall a Premier League statistic from last season: players under 23 in the top 20% of touches per match showed far greater development curves than those averaging fewer than 40 touches. Not because they were more talented, but because they were given more responsibility. Responsibility creates maturity. If U22 Vietnam goes to SEA Games with the mentality of "waiting for the opponent's mistakes," we are stripping these young players of the right to decide their own fate. Some will argue that Thailand at SEA Games is also not playing beautiful football, and Indonesia is bringing in quality naturalized players. True—which is exactly why U22 Vietnam needs its own identity. If we try to copy Thailand's possession, we will lose to them at their own strength. If we copy Timor-Leste's defensive resilience, we will lose at our own weakness. The answer lies in between: a proactive style that dares to press, dares to build with short passes, yet stays alert when losing the ball. Look at how Nam Định won the 2026-24 V-League. They were not the team with the most stars or the biggest budget. But they dared to play possession football in a league where most teams choose counter-attacks out of fear of dropping points. Nam Định accepted risks, accepted losing a match or two because they pushed forward, and by the end of the season they had built a unit that understood each other down to every square meter of the pitch. That is what U22 Vietnam needs to construct—not a one-off tactic for a single tournament. I once interviewed a young English coach who said: "4-2-4 is not a formation, it is a test of who dares to dream." That sentence echoes in my mind whenever I watch Southeast Asian teams play utilitarian football to the point of dryness. We have the right to dream of a generation of Vietnamese players who can dominate opponents with technique and intelligence, rather than merely waiting and punishing. At the upcoming SEA Games 33, if U22 Vietnam wins by parking the bus, I will celebrate with everyone. But deep down, I will worry about the future. Because a generation that only knows how to win through safety will never have the nerve to conquer bigger stages—where opponents are no longer Thailand or Indonesia, but Japan, South Korea, and Iran. Let U22 Vietnam be allowed to make mistakes, to learn, and to play the football they believe in. Let young coaches boldly build a possession-based style, knowing there will be painful last-minute defeats. Because if we keep living in the memory of the 2026 ASEAN Cup victory, we will lose the most precious thing football gives us: the ability to dare to dream of a different future. What I want to say is not about tactics. It is about belief. Youth football is not just matches for medals—it is where we nurture people who think big, take responsibility, and rise after falling. If U22 Vietnam can learn that from SEA Games 33, whatever the result, we will have truly won. On the empty night at the Etihad in 2026, I heard my own applause most clearly. Football without spectators taught me: what remains in the end is not the trophy or glory, but the people and how they face themselves. U22 Vietnam should remember that before stepping onto Southeast Asia's biggest stage.
