All three Celtic goals came from substitutes. Osmand restored parity after Junior Olaitan put Besiktas ahead from the penalty spot, following a challenge by Jordan Lotomba. Duran then struck to give Celtic the lead, only for Orkun Kokcu to bring Besiktas level.
Duran’s second goal completed the comeback. The impact was immediate and decisive: Osmand changed the score with his first touch, while Duran supplied the two goals that carried Celtic from behind to victory.
Celtic’s route to the points was not straightforward. They conceded first, recovered, lost their advantage and still found a winning goal. That sequence makes the result more than a breakthrough in the competition; it gives the side evidence that its bench can alter the course of a tight European match.
The finishing, rather than control of the contest, proved decisive. After Besiktas made it 2-2, Celtic needed one more answer-and Duran provided it.
Celtic will now look to carry that late resolve into their next European outing. The contribution of Osmand and Duran also gives the manager a timely reminder: fresh options can be more than cover when a match starts to turn.
