But with Bayern virtually assured of progression after a 5-0 home win in the first leg, the highlight of the match was arguably a ginger cat briefly interrupting the action in the second half.
The German side went ahead through Thiago Alcantara in the 18th minute with the Spaniard volleying in a Thomas Mueller cross to kill off any lingering hopes of a miracle recovery by the Turkish team after Bayern had crushed them 5-0 in the first leg in Munich.
