Aberdeen got the game underway and competed well in the opening stages with neither team able to carve out a chance in the opening five minutes. Mackie conceded a free kick in a dangerous area in the 6th minute but it was well defended then a minute later Heikkinen did well to block a Valgaeran effort as Aberdeen contained the early pressure. The Dons created a half chance in the 10th minute as Blaha and Byrne combined before they won the first corner of the match. The set play produced the opening goal when Clark's corner was half cleared allowing Severin to return the ball into the danger area where Diamond steered the ball past Marshall from 15 yards.
Richie Byrne collected the first yellow card in the 13th minute when he tugged the shirt of Petrov. The set play was well defended and Aberdeen broke quickly to add a sensational second goal when Heikkinen released Muirhead who ran the length of the field and found Mackie in the clear. The striker made no hesitation as he drilled the ball past Marshall. Aberdeen were now full of confidence and won another corner in the 17th minute when a McNaughton shot was headed wide. The Celtic defence dealt with the set play however as they suddenly found themselves on the back foot. Celtic almost pulled a goal back in the 21st minute when Bellamy released Petrov but Esson was out quick to smother the ball.
Aberdeen almost added a third in the 31st minute when a cross-come-shot hit the roof of the net from Muirhead. Aberdeen were under the cosh again in the 36th minutes before Esson managed a secure punch to clear the danger then an error by Diamond two minutes later produced another corner, which ended with Hartson firing over the bar. Hart conceded a free kick 30 yards out in the 44th minute but the wall held well and mopped up. Despite two minutes of injury time the Dons held out comfortably to the break.
Celtic came out after the break with all guns blazing as they looked to level the match although the Dons did break out in the 49th minute but were unable to penetrate the home defence. A minute later Esson made a great save from Bellamy but the danger wasn't cleared and Hartson pounced to level the game after firing in an Agathe pass to punish some sloppy defending. The great start had now been undone with still forty minutes of the match remaining. Aberdeen broke again in the 54th minute as Blaha moved forward but was halted for a very soft infringement. A minute later good build up play set up McNaughton but the midfielder chipped the ball over the bar with Marshall off his line.
In the 67th minute Severin strode forward but failed to find Foster with his pass as the Dons looked for an equaliser. Two minutes later Esson easily gathered a Varga header before a poor pass from Heikkinen halted a potential attacking opportunity for the Dons. Seconds later another Severin cross caused problems for the home defence before Byrne was replaced by McGuire in the 72nd minute. Four minutes later a Muirhead cross just evaded Mackie as the Dons continued to probe for a way back into the game. Agathe was lucky to escape a booking for a late challenge on McNaughton in the 80th minute as the Dons continued to force the game.
With eight minutes remaining Aberdeen forced a period of sustained pressure as Celtic looked to desperately hang on to their lead. In the 83rd minute Mackie was found at the back post but his header back across goal was intercepted by Marshall. Then with two minutes left on the clock Calderwood replaced McNaughton with Jamie Winter as the Dons looked for another late goal in paradise. In the 90th minute Foster broke again and slipped the ball to Mackie but the ball was adjudged to have crossed the line before he delivered. In the closing seconds Muirhead had the chance of glory but fired well wide of the target.
