The 2026 U19 Southeast Asia tournament will feature a rather unique competitive format, selecting only four teams for the semi-finals: the three group winners and the best runner-up. This is predicted to make the group stage race extremely tense.
According to the tournament regulations, the top teams of Groups A, B, and C will each earn a direct spot in the semi-finals. The remaining ticket goes to the runner-up with the best record among the three groups.
However, since Group C has only three teams, AFF applies specific rules to ensure fairness. Specifically, when comparing the records of the runners-up, the results of the runners-up from Groups A and B against the last-placed team in their group will not be counted. This means that goal difference and goals scored in major matches will play a crucial role.
The criteria for determining the best runner-up are, in order: points, goal difference, goals scored, number of wins, and finally fair-play points.
In the semi-finals, the winner of Group B will face either the winner of Group C or the best runner-up from Group A or C. Meanwhile, the winner of Group A will face the winner of Group C or the best runner-up from Group B.
Notably, Group C consists of only three teams: Australia, Cambodia, and the Philippines, so the runner-up from this group's chance of reaching the semi-finals will greatly depend on its ability to build a strong goal difference.
The 2026 U19 Southeast Asia tournament takes place from June 1 to 14 in Indonesia, featuring 11 top regional youth teams. Vietnam U19 is in Group A alongside hosts Indonesia, Myanmar, and Timor-Leste. Among them, the match against Indonesia on June 7 is considered a "group final" that will decide the top spot.
