At 2-0 down, Celtic were staring at the invidious scenario of a box-ticking exercise in Munich next week. Their response, clawing their way back into this tie via Daizen Maeda, permitted fresh hope.

Bayern Munich will remain the favourites to progress to the last 16. Indeed, for 78 minutes they looked irritated at being forced to play an extra couple of games to get there. Yet Celtic are due praise for their refusal to wilt against such stellar opposition. They will believe they can cause further Bayern scares in the Allianz Arena.
