As Vietnam had already secured a spot in the semifinals, coach Park Hang Seo decided to deploy his reserve line-up in this game.
Despite having the advantage over Timor Leste, the Golden Stars were unable to net any goal in the first half.
Nguyen Van Tung opened the scoring for Vietnam in the 53rd minute with an accurate header following a pass from Le Van Do.
Timor Leste boosted their offensive and were able to strike Vietnam’s net in the 56th minute, but the goal was disallowed for offside.
Vietnam were given a corner kick in the 65th minute, allowing Ho Thanh Minh to widen the gap for the Golden Stars with another header.
No more goals were scored in the remaining time of the match.
