The Phobians at the Accra Sports Stadium suffered a 2-0 defeat in the matchday 18 games.
Isaac Mintah’s second-half brace on the 47th and 64th minute powered the Aduana Stars to extend their lead at the top to five points.
Speaking in an interview after the defeat, the Serbian tactician stated they got punished for being wasteful after missing six to seven clear cut opportunities that fell on their path. He said.
“We have a lot of chances. If you count we have 6 or 7 chances. You didn’t score goals and they punish you,” he said.
“Sometimes when you don’t score mentally the team goes down and I think that happened today,” he added.
The Rainbow Club have dropped two places on the league table after 18 matches and now sit 4th on the league log with 28 points.
