Cambodia's Preach Khan Reach (PKR) FC marked their entry into the M-League with a sluggish 2-1 victory over Penang in Saturday's FA Cup first round match.
Prior to the team's arrival in Kuala Lumpur two days ago, the players did not train as they were more interested in partying following their 2-1 victory over NagaCorp FC to retain their Hun Sen Cup on Feb 12.
Coach Sam Vandeth said his players partied continuously before boarding the flight to Kuala Lumpur.
"My players did not give their best today (Saturday) as they were tired. We partied a lot after our success in the Hun Sen Cup," Vandeth said at the National Stadium in Bukit Jalil on Saturday.
"We are, however, happy to make a winning start in the FA Cup. Malaysian football is on the rise and we are honoured to be playing in this tournament.
"My team only had two days of practice before this match. We will be better prepared for the second round."
After making several schoolboy errors inside Penang's penalty box, PKR finally took the lead in the 28th minute through Phanny Ratha before Prak Mony Udom added their second by latching onto a through pass before flicking the ball over goalkeeper Shukor Abd Malek in the 86th minute.
Penang captain Hasmawi Hassan scored a consolation goal two minutes before time.
PKR will face KL SPA FC in the two-leg second round tie on March 2 and 10, while Penang make their debut in the FAM League on March 4.
