The first half saw both sides adopting a cautious approach with chances few and far in between.

Phnom Penh centre-back Jang Bo-jeong had a go from a free-kick 30 yards out but it lacked the power to trouble Ng Cheuk Wai.

TSL looked to attack mainly through Isabella Bandoja on the right flank, the Filipino winger dribbled past two in the box before her shot was blocked by Vibol Serysitha and a header in the 31st minute went wide.

The Hong Kong side kept going and were rewarded on the stroke of half-time, Lucia Ko delivered a pinpoint corner delivery to the back post for Liao Meixin to head past Chea Fariya.

TSL looked the likelier to add to the score after the interval with custodian Fariya required to be at her best in the 56th minute to make a double save to thwart Ko then Anke Leung on the rebound.

Phnom Penh’s opportunity came from set-piece with Poeurn Kunthea’s 73rd minute free-kick sailing just over the bar and seconds later they went further behind.

A quick counter saw Liao slipping Wong Hiu Ting into space but while Fariya blocked the strike, she could do nothing to prevent Tsang Lai Mae from sweeping home the rebound.

Serysitha tried her best to help Phnom Penh claim at least a consolation goal but saw her 89th minute cross tipped onto the post by Ng as TSL kept a clean sheet to go with their victory.
