Hearts of Oak coach Mohammed Polo blamed the 3-0 defeat at Wa All Stars on poor markin by his players.
Dennis Adusei opened the scoring in the 25th minute before two-goal hero Paul De-Vries Asare scored the second ten minutes later for the Wa-based club.
Polo conceded that All Stars were ruthless in front of goal.
“We left them too many spaces. All Stars then caused us a lot of damage with those spaces. All Stars did well, they took their chances and that was their luck," Polo said.
"I must try to get my team working again. We will play a more cohesive game in the second round and get back to winning ways."
Polo has lost one, drawn one and won one game since he took charge of Hearts of Oak in November.
The Phobians have dropped to third on the league log with 27 points after the defeat.
