Harry Kewell calls it rock and roll under Ange Postecoglou but the Celtic boss might feel more like singing the blues after this Champions League campaign.
Or perhaps more like a wistful country and western crooner with a tale of woe and wishful laments for what might have been. It was a now familiar tune last night. Celtic hit the high notes a couple of times but were punished when they were off-key for a second.
That’s all it took for things to turn flat again. Reo Hatate’s loose pass in midfield, a couple of seconds later and the ball was fizzing into Joe Hart’s net. Up to that point it was easy listening for Celts. Giorgos Giakoumakis proved again why he’s the Parkhead side’s best front man and the Hoops were on course to finally get the win they craved to keep the Europa League miracle alive.
