In the 27th minute, Thailand coach Naruephon Kaenson put forward Taneekarn Dangda onto the field to replace Jaruwan Chaiyarak in a bid to strengthen their attacking power.
However, the substitution did not really work as Thailand continued to play on the back foot in the remainder of the first half. They failed to create a single clear-cut chance and had to count on long-range shots hoping to break the deadlock.

Kaenson’s troops produced a strong start to the second half, with Taneekarn Dangda testing goalkeeper Kim Thanh with a shot at the centre of the box in the 48th minute.
The substitute went on to prove her value by burying the ball in the back of the net three minutes later. However, it was lucky for the Vietnamese side as Taneekarn’s goal was disallowed for offside.
Keeper Kim Thanh rescued Vietnam again six minutes after the hour mark making a smart save from a close-range header.
With time running out, the agility of Tuyet Dung in the left wing inspired Mai Duc Chung’s side to produce a number of dangerous attacks on Thailand’s goal, but Huynh Nhu and Bich Thuy failed to manage a shot.

The goalless result remained unchanged despite concerted efforts from both teams, forcing the match into extra time.
Vietnam’s constant attacks paid off in the second minute of extra time, as a Thai defender managed to parry a left-wing corner kick by Tuyet Dung but unexpectedly created a favourable pass to Hai Yen. The second-half substitute made successful use of this golden opportunity to seal a late winner for Vietnam with a powerful header from close range.
With the narrow victory, Vietnam successfully defended their SEA Games title, thus continuing to solidify their women’s football reign in Southeast Asia.
