Celtic went into the interval 2-0 down thanks to goals from Hincapié and Diaby. The first goal was particularly poor with David Turnbull suffering from a horrible mistake in the Celtic box before Bakker cut the ball into the path of the forward, who made no mistake from close range.

It was a goal that really upset the Celtic rhythm. Before that, Kyogo had a couple of good chances and was denied by Tah & the Finnish goalkeeper.
