"I am so proud that we came out of the shadow (from the draw) with a brilliant performance and delivered under pressure.

"This win has significantly relieved our pressure. Now we have the chance of qualifying into the next round held tight by ourselves and we are looking forward to put on another good performance facing Thailand in the next game," said Wu, who played for La Liga's Espanyol from 2018-2022.

Wu's 21st-minute opener for China was followed by an instant equalizer by a Faris Ramli header in the very next minute in the first half, but second half goals from Fei Nanduo's spot-kick, a second from Wu, and a late strike from Wei Shihao dampened Singapore's surging attempt for another comeback.
