The only score in the match was made at the 25th minute of the game by Theerathon Bunmathan.

The first leg taking place at Vietnam’s My Dinh Stadium ended with a 2-2 draw.

In the history of the AFF Cup, Vietnam and Thailand had only met in the finals once, in 2008, when Vietnam was crowned champions for the first time. Thailand currently has the most AFF Cup trophies (formerly known as Tiger Cup), having won seventh times.
