Vietnamese Football: Winning Through Set Pieces and the Unresolved Question of Identity

On the night of January 5, 2026, at Rajamangala Stadium in Bangkok, the final whistle blew with the scoreline reading 3-2 in Vietnam's favour in the second leg of the ASEAN Mitsubishi Electric Cup final. A 5-3 aggregate over two legs, and Vietnam's third title in the history of the regional competition. What I remember most is not the goals, but the moment before the ball was delivered into the box. I watched the match from a small room, through a screen, with the sound of traffic outside. I noticed a detail the media rarely gives enough airtime: before every corner, Vietnam's defensive line did not stand still. They moved according to a pattern, dragging opponents out of position, then attacking the space that opened up. When the ball goes dead, I start reading the game. For nearly two decades, Vietnamese football built itself a beautiful story: small, technical play, emphasising combination in tight spaces. People spoke of Nguyễn Quang Hải, of delicate touches, of a Vietnamese identity as a cultural category rather than a tactical one. That story has appeal. It sells tickets, creates emotion, and bonds fans. But it also has a hole: it cannot explain why the national team often gets stuck against Southeast Asian opponents who press hard and defend tight. When coach Kim Sang-sik arrived, he did not tear down the technical philosophy. He added another layer: organisation in set-piece situations. This is something many teams in the region neglect, because it is not pretty, it does not produce viral clips, but it decides results in big matches. The hero of that journey, Nguyễn Xuân Son, is not a flamboyant player. He is a striker with the ability to choose positions inside the box, read the flight of the ball, and exploit the spaces opposing defences leave open. That is the archetype modern football calls a box poacher: he does not need many touches, only the right one. I once spent a summer in 2026 compiling statistics from 50 Liverpool matches under Jürgen Klopp. The result: 14 of their 37 goals, or 38 percent, came from aerial play after set pieces, including 6 headed goals by Virgil van Dijk. That statistic made me rethink how I read football. And when I applied the same method to Vietnam at the 2026 ASEAN Cup, I found a similar pattern: the team did not need to control the ball to win; it needed to control the moments. Three tactical elements stood out in that operation. First, the ability to create pressure in the box from corners. Vietnam did not deliver the ball randomly. They aimed for the zone between the goalkeeper and the far post, where the keeper finds it hardest to come out and defenders lose their markers. Second, using the striker as a decoy to drag the defensive line, opening space for the second line to run into. Nguyễn Xuân Son was frequently marked by two defenders, and that very fact created space for midfielders such as Nguyễn Quang Hải or Nguyễn Hoàng Đức. Third, the ability to switch quickly after winning the ball. Vietnam did not hold possession long. They moved it toward the opponent's goal within seconds, before the defence could reorganise. The majority look at the star; I look at the space. If you only look at Nguyễn Xuân Son, you see a striker scoring goals. But if you look at the space behind Thailand's defensive line in the second leg of the final, you see an entire system at work: midfielders pulling the ball wide, full-backs pushing up, and the striker waiting for the right drop point. Everyone knew where they had to be, and that is something you cannot teach in a single training session. What is interesting is that this style runs counter to the image Vietnamese media usually builds. People want to see elegance, they want to see short combinations. But in modern football, elegance does not have to be pretty. It can lie in choosing the right moment to deliver a cross, or the right moment to hold the ball instead of charging forward. In the group stage, Vietnam already showed signs of a team that knew how to manage matches. They did not need big wins to make an impression. They won enough, and saved energy for the knockout rounds. That is the mindset of a big team, rather than one that plays purely on inspiration. Thailand, with its tradition of possession football, was one challenge. Indonesia, with a squad of naturalised players, was another. Vietnam had to solve two opposite problems within a single tournament, and they did it by adapting rather than clinging to a single idea. By the semi-finals and the final, as the pressure rose, that tactical essence became clearer. The goals came from situations that were not flashy but effective: corners, quick counter-attacks, and second balls inside the box. A strong national team needs a domestic league competitive enough to develop players. In Vietnam, the V.League is struggling with familiar problems. Attendance is low. Many matches draw only a few thousand people, while major national team games can fill Mỹ Đình Stadium with tens of thousands of fans. That gap says a great deal about the appeal of club football. Club finances are unstable. Many teams depend on a few wealthy owners, and when an owner withdraws, a club can vanish within months. The story of clubs that won titles and then dissolved remains a warning. Dependence on high-quality foreign players creates a paradox. Clubs sign foreigners to compete immediately, but that can take opportunities away from young players. A league where key positions are all filled by foreigners will struggle to produce domestic strikers of sufficient quality. At youth level, Vietnam has well-invested academies. The PVF academy, HAGL-JMG, and Viettel's youth setup have produced many national team players. But the numbers are not yet enough to generate a stable next generation, and many young talents fade away when there is no top-level match environment. This is where I challenge myself. There is a major risk when a team depends on set pieces and a naturalised striker: the danger of being figured out. Opponents in the region will soon analyse the footage, find the pattern, and adjust. When that happens, Vietnam will need a Plan B that does not rely on dead balls. Placing too much expectation on Nguyễn Xuân Son is a double-edged sword. One player can carry an entire attack for a tournament, but cannot carry an entire cycle. If he is injured, or if opponents neutralise him, the team will expose a large gap. I also noticed the story of refereeing and VAR. The V.League has introduced VAR, but the mechanism for explaining decisions on the pitch is still lacking. Fans in the stands often do not understand why a goal was disallowed, and that creates a sense of injustice. Transparency demands more than having the technology; it requires a way of communicating that technology to the viewer. From a business angle, I also see a problem. Global sponsors pour money into football because of brand exposure metrics, not because they are attached to local communities. When the logo on the shirt changes every season, the bond between club and local fans loosens too. That is the price of commercialisation. Modern football has no randomness, only data that has not yet been read. And the data on Vietnamese football is telling us one thing: the national team is moving faster than the domestic league. That gap is a long-term risk. If I had to bet on one thing for Vietnamese football in the coming years, I would bet on its capacity to transform. The national team has proven it can win through structure, not purely through inspiration. The remaining question is whether the V.League can keep up. What I want to see next is a V.League where club matches can fill stadiums without needing the national team as bait. That is the true measure of a footballing nation. Winning is a moment. Identity is a process. And that process has only just begun.
