Bayern Munich will have hoped to build an unassailable advantage when going 2-0 up just after halftime, but instead were forced to hang on as Celtic came up just short in a late comeback bid.

Wednesday's UEFA Champions League action was all about tight margins, with four teams carrying a one goal advantage into next week's second leg of the knockout phase playoffs after tightly contested matches.

Celtic are playing in their first Champions League knockout tie in 12 years, with their last coming in a 3-0 defeat to Juventus in February 2013. The Scottish champions benefited from the changes to the Champions League format and finished the league phase in 21st position – with ten of their 12 points coming at Celtic Park.
