Six minutes before the half-time break, the visitors took the lead through Zlatko Tripic who powered the ball past goalkeeper Ersin Destanoglu after Peter Zulj’s initial effort had rattled the crossbar.
After the recess, the hosts equalised through Ljajic in the 49th minute before Cameroonian Vincent Aboubakar bagged the match-winner for the Black Eagles in the 77th minute.
