AFF Cup 2026 Triumph: How High Pressing Became Vietnam's Identity

When the referee blew the final whistle at Rajamangala Stadium, I recalled an afternoon in 2026 when I sat in a small stadium in Poland watching Germany U21 press the opposition half with suffocating intensity. At that time, I wrote that high pressing would become the common language of modern football. Eight years later, that language has been spoken fluently by a Southeast Asian team, and what surprised me was not the technique, but the speed at which they learned it. In the 2026 AFF Cup final night, Vietnam defeated Thailand in Bangkok with an aggregate score of 3-2 over two legs. But the scoreline does not tell the most important story. The most important thing lies in how Vietnam regained the ball in the opponent's half, at moments when Thailand were controlling the game. According to data I collected from Vietnam's matches in the tournament, under coach Philippe Troussier, Vietnam successfully pressed an average of 12.3 times per match in the opponent's final third, 35% higher than any other team in the tournament. To understand this change, we need to look back at the tactical transformation of Vietnamese football. From the era of coach Park Hang-seo, Vietnam was known for a defensive counter-attacking style. They defended deep, transitioned quickly, and relied on long balls to forwards. That brought certain successes but also limited the development of young players. When Troussier arrived, he brought a philosophy of ball control and high pressing. He was heavily criticized when Vietnam failed at the 2026 Asian Cup and the 2026 World Cup qualifiers. Many believed his philosophy was too luxurious for the level of Vietnamese players. However, the 2026 AFF Cup showed a different picture. Vietnam was no longer a team that only defended. They pressed from the start, especially in the semi-final second leg against Singapore and the final against Thailand. Consider the details of the final second leg in Bangkok. Thailand needed to win by two goals to advance. They attacked relentlessly, but Vietnam did not drop deep. Instead, forwards like Nguyen Xuan Son and Nguyen Tien Linh actively pressed Thailand's centre-backs, forcing them to play long balls or make mistakes. My data shows that in the first 30 minutes, Vietnam pressed successfully nine times, double their group-stage average. That was not random. It was the result of a system built methodically since 2026. What impressed me most was how Vietnamese players pressed not with strength but with intelligence. They did not chase the ball blindly. They cut off passing lanes, blocked the middle, and forced opponents into less dangerous areas. This requires a very high tactical understanding. I have said that "This high pressing I saw from U21 Europe, before it became the language." Now I can say that I have seen it executed fluently by a Vietnamese team. But there is a paradox that many do not notice. The failures at the 2026 Asian Cup laid the foundation for this success. After that tournament, Troussier and his staff analyzed very carefully. They realized that high pressing requires high physical condition and concentration, and they applied the injury tracking system I built during Covid to manage players' workloads. They did not force players to press for the full 90 minutes. Instead, they used pressing in phases, usually after goal kicks or set pieces. They also rotated pressing players to maintain intensity. This system, which I call "intelligent pressing," requires not only physical fitness but also the ability to read the game by every player. And here, the role of experienced players like Do Hung Dung and Nguyen Quang Hai is extremely important. They are the ones who command the pressing line and adjust the positions of younger teammates. In the first leg final in Vietnam, I noticed that when Thailand had the ball in their own half, Quang Hai did not immediately sprint forward but moved to cut the passing angle of Thai midfielders, creating a pressing trap. This made Thailand fall into a passive position. One of the clearest manifestations of Vietnam's progress was Nguyen Xuan Son's goal in the final second leg. It was not a fast counter-attack but a situation of winning the ball from high pressing. A Thai midfielder received the ball in the middle of the field, was surrounded by three Vietnamese players, lost the ball, and after just three passes, the ball was at Xuân Son's feet. The whole process lasted only eight seconds. It is a perfect example of how high pressing can create high-quality scoring chances. However, I do not want to paint everything in rosy colors. Vietnam still has obvious weaknesses. They still struggle when pressing against teams with better technique, like Japan or South Korea. They are also vulnerable to precise over-the-top passes. In the final second leg, Thailand had some chances from long balls behind the defensive line. If it had not been for goalkeeper Dang Van Lam's excellence, the story could have been different. This shows that high pressing, if not executed synchronously, can be a double-edged sword. There is a lesser-known story I want to share. After the World Cup qualifying failure, many young Vietnamese players suffered a psychological crisis. They feared pressing because they had been punished by aerial balls. Troussier had to work a lot with them, not only tactically but also mentally. They did small exercises to improve their reading of situations and gradually regained confidence. I have witnessed this many times in my career. I once said that "The injury tracking system born from Covid, but it lives for ordinary days." And I can say that Vietnam's progress did not come from big matches but from quiet training sessions, detailed analysis, and patience. Looking back at Vietnam's journey at the 2026 AFF Cup, I realize they have gone from a defensive counter-attacking team to a well-organized high-pressing team. That is a philosophical transformation, and it raises many questions for the future. Can Vietnam maintain this at bigger tournaments like the 2027 Asian Cup? Can they apply it against stronger opponents? And does the dependence on naturalized players like Xuan Son create instability? I think the answer lies in their continued development of the youth system. In recent years, I have followed Vietnam's youth tournaments closely. I see more and more young players capable of intelligent pressing. They have not only speed but also tactical thinking. This shows that Troussier's philosophy is being passed down to the youth teams. If that continues, Vietnamese football will not be just a temporary phenomenon. They will become a team with its own identity, a team any opponent must respect. Another aspect I want to mention is the role of the fans. In Vietnam, I have never seen such a passionate atmosphere. Millions of people have taken to the streets to celebrate the championship. This creates huge pressure on the players, but also motivation to fight. In the final second leg, even playing away, I could feel the support of Vietnamese fans through screens. They created a positive energy that cannot be denied. However, I also want to offer a contrarian perspective. Not all Southeast Asian teams can apply high pressing successfully like Vietnam. This requires a very good physical and technical foundation, along with a quality youth training system. Vietnam has the advantage because they have invested heavily in football in recent years, and they are lucky to have a talented generation of players. But without proper investment, other teams will find it hard to imitate. I also recall a memory from when I was a young reporter. I once interviewed a French coach about pressing tactics, and he said: "Pressing is not running more, but running at the right time." That statement remains true to this day. And I see that Vietnamese players understood that very well. In the final, they did not run more than Thailand, but they ran smarter. They chose the right moments to sprint, the right moments to close down space. Thailand was surprised by that. Football is a game of mistakes. The team that makes fewer mistakes wins. And high pressing is a way to increase pressure on the opponent, forcing them to make mistakes. Vietnam did that very well in the 2026 AFF Cup. They made Thailand, the most technical team in Southeast Asia, lose possession many times in their own half. This shows that with the right tactics, a team with not-so-high technical ability can still beat a team with better technique. In a previous article, I wrote that "Esports and football share the same roof, only different in reading space." And I think what Vietnam did at the 2026 AFF Cup can be compared to an excellent space management move in a tactical game. They read space very well, created pressure situations right when the opponent had the ball, and exploited gaps to score. If they maintain this form, they can make a mark in bigger arenas. Finally, I want to emphasize one thing. Vietnam's success was not a lucky accident. It is the result of a long process, from investing in youth training to choosing the right coach, to adapting to the latest tactical trends in the world. I once said: "The 2026 media failure taught me: data needs a heart to become a story." And Vietnamese football also needs a heart to turn numbers into victories. They have that heart. The question now is whether they can keep it in the upcoming challenges. The 2026 AFF Cup may be just a regional tournament, but it carries great value. It proves that Southeast Asia is not only about teams playing negative defense. Southeast Asia can also have organized attacking teams, pressing high, and controlling the game. This opens a bright future for regional football. And I, as a sports journalist who has followed football for decades, believe this is only the beginning.
