Striker Huynh Nhu and captain Tuyet Ngan took the game by the scruff of the neck, and at the 10th minute Ngan scored from a free kick, launching an avalanche of attacks on the Singapore goal.
The second goal came in the 14th minute from Xuan, and just minutes later, Ngan got her second of the match.
Nhu continued to terrorise the visitors’ defence and score a further three goals before half time.
The Singaporean defenders did not have it much easier after the break, and a fumble by the Singaporean goalkeeper presented Nhu with another goal at the 50th minute.
Ngan, Vu Thi Hoa and Thu Xuan (twice) rounded off the scoring, with barely a threat to their own net.
In the group’s opener on October 24, the Vietnamese team also defeated Malaysia 2-1.
With two wins, Vietnam’s U19 women squad is currently top of their group above Jordan, who beat Malaysia 2-1.
In the next match against Jordan on October 28, the Vietnamese women will only need to secure a point to ensure top place and secure a place in the knock-outs.
