After the 2026 ASEAN Cup Title, Vietnamese Football Faces a Bigger Question

On the Rajamangala stands on the evening of January 5, 2026, thousands of Vietnamese fans sang out in the heart of Bangkok. Vietnam had just beaten Thailand 3-2 in the second leg, sealing a 5-3 aggregate victory in the two-legged ASEAN Mitsubishi Electric Cup final. It was the third time Vietnamese football had been crowned champions of the region, after 2026 and 2026, and the first title for coach Kim Sang-sik since he took charge in May 2026.

The joy is real, and it is fully deserved. But looking a little further ahead, Vietnamese football fans are forced to confront an uncomfortable reality: success in Southeast Asia is becoming increasingly routine, while the dream of reaching continental and world level remains very distant.

The blemish behind the trophy

Only a few months before lifting the trophy, Vietnam had endured a disappointing 2026 World Cup qualifying campaign. Drawn in a group featuring Japan, Australia, Saudi Arabia, Bahrain, China and Indonesia, Kim Sang-sik's side could not compete for a place in the next round. A string of defeats against stronger opponents showed that the gap between Vietnamese football and Asia's leading group has not been closed.

Notably, this contrast is nothing new. In 2026, Vietnam won the AFF Cup under coach Park Hang-seo, then went deep at the 2026 Asian Cup by reaching the quarter-finals. But afterwards, the team could not sustain that momentum in World Cup qualifying. Vietnamese football appears stuck in a loop: shining in the region, struggling on the continent. The dismissal of coach Philippe Troussier in March 2026 after a defeat to Indonesia was clear evidence of that instability.

Nguyen Xuan Son and the question of dependence

The most important factor in the 2026 ASEAN Cup triumph was naturalized striker Nguyen Xuan Son. The Brazil-born player scored in the first leg of the final, playing a major role in giving Vietnam an advantage over Thailand. In the second leg, he shone again before suffering a serious leg injury, forcing him off the pitch on a stretcher amid the whole team's anxiety.

The dependence on Nguyen Xuan Son raises an important tactical question: is Vietnamese football building its game around an individual rather than a sustainable system? When Xuan Son suffered a long-term injury, the team's attack immediately lost its anchor. Domestic strikers like Nguyen Tien Linh remain reliable goalscorers, but the burden of scoring in big matches still falls heavily on a handful of names.

Using naturalized players is not something to be condemned. Many developed football nations have done the same, and Indonesia itself is pursuing a large-scale naturalization strategy aimed at the 2026 World Cup. The issue lies in the fact that a national team is only truly strong when it can adapt without depending on any single individual.

Kim Sang-sik and the tactical imprint

Under coach Kim Sang-sik, Vietnam have made notable adjustments. The Korean manager prioritizes balance between attack and defence, while maximizing the pace of his wingers. At the 2026 ASEAN Cup, Vietnam displayed a disciplined style, knowing how to control matches and take their chances.

However, that style is still not enough to compete with Asia's top teams. Against stronger opponents, Vietnam often struggle to build play from the back and maintain control of the game. This is a systemic problem that cannot be solved by a few matches alone.

V.League and the gap in standards

At club level, the V.League remains a competition with great appeal for domestic fans. But the professional quality of the league is a barrier to the development of Vietnamese football. Domestic clubs frequently change coaches, lack tactical stability, and rely heavily on foreign players to decide matches.

That instability directly affects the national team. When young players are not playing in a properly structured tactical environment, their ability to adapt on the international stage is limited. World Cup qualifying matches, where the speed and intensity are far higher, often expose weaknesses that domestic football cannot hide.

In addition, facilities and youth training have improved considerably, with academies such as PVF and Hoang Anh Gia Lai making no small contribution. However, the path from academy to national team remains difficult, and not every young talent gets the chance to develop in the right direction.

The fans' faith

Football has always held a special place in the spiritual life of Vietnamese people. Whenever the national team takes the field, millions of fans pour onto the streets to celebrate. That passion is a priceless asset, but it is also considerable pressure on the players and the coaching staff.

Vietnamese fans deserve to see their team go further on the continental stage. And to achieve that, Vietnamese football needs more than victories in the region.

What is the solution?

The answer for Vietnamese football perhaps does not lie in changing coaches or seeking more naturalized players. It lies in building a football philosophy that runs through everything, from the national team to youth levels, from the V.League to the training centres.

Successful football nations in Asia such as Japan and South Korea have followed a similar path: staying committed to a philosophy, investing properly in youth development, and creating a healthy competitive environment in the domestic league. Vietnam has enough potential and passion to do the same, but it needs patience and long-term vision.

The 2026 ASEAN Cup title is a proud moment, and fans have every right to celebrate. But if Vietnamese football stops at conquering Southeast Asia, the dream of reaching continental level will remain just that: a dream.
