Hoang Hen gave Vietnam the perfect start in the seventh minute when he steered a left-foot shot beyond Dylan Niski while Dinh Bac hit his side’s second as he bent a fine finish into the bottom corner in the 31st minute.

Hoang Hen scored Vietnam’s third with four minutes left in the half while Dinh Bac poked home from close range two minutes later and Xuan Son bundled the ball over the line in the first minute of stoppage time.

Dinh Bac completed his hat-trick in the 65th minute when he steered Bui Hoang Viet Anh’s cutback beyond Niski while Farrugia’s own goal completed Timor-Leste’s misery with 11 minutes remaining when he sliced in Nguyen Quang Hai’s shot on goal.

Singapore needed a spectacular stoppage time winner from Ilhan Fandi to secure their win over Cambodia after seeing Shawal Anuar’s 22nd minute opener cancelled out by Ouk Sovann 10 minutes into the second half.

Shawal smashed his shot past Hul Kimhuy when he had been released behind the Cambodian defence by Lionel Tan’s incisive pass from deep but Ouk had levelled the scores in the 55th minute with a well-struck effort that gave Izwan Mahbud little chance.

The game appeared destined to end in a stalemate until the 11th minute of added time when Ilhan flicked Song Ui-young’s pass into the air and launched an unstoppable right-foot volley beyond the helpless Cambodian goalkeeper.
