Kilmarnock 1-1 Copenhagen (1-3 agg): Analysis
Boss Derek McInnes said he wanted this game to become a "nightmare" for Copenhagen and, for a while, it was.
They pressed their opponents high from the first whistle, making the game really uncomfortable for the Danes, who started to look nervy.
They got their reward for it - unsurprisingly from a set-piece - but the cracks started to show after the break.
They couldn't keep that relentless energy up and stepped a yard off Copenhagen, who took full advantage of the extra time and space to click into gear, playing the game they wanted it to be played.
It's been far from the dream start to the season for Kilmarnock. They've struggled for fitness and had to rotate heavily because of the demand of European games.
However, they can leave Europe with their heads held high after a few battling performances. They need to show that grit in the league now - just like they did last season.
