SINGAPORE - Phnom Penh Crown's chance of moving on to the semifinals of this year's Singapore Cup now hangs in the balance after the team suffered a 2-1 loss to Bangkok Glass in Wednesday's first leg. Crown made a flying start when Chan Chhaya opened scoring inside nine minutes. The Cambodian flag-bearers kept hold of the lead until the 40th minute, when Glass equalised through Chatree Chimtale. Both sides came out in the second half looking for the winner, with Crown bringing on Lor Pichseila for Ek Sovannara, while the Thai side responded by making double changes. It was the Thai side that made the most of the tactical changes, with substitute Mathee Pungpo producing the winning goal in the 53rd minute. Crown now need to win the second leg next Wednesday in Singapore to advance to the next round.
