Robert Lewandowski scored again as Bayern Munich reached the Champions League knockout stages with a 2-0 victory over Olympiakos on Thursday in the club's first game since coach Niko Kovac was fired.
Ivan Perisic added a late goal for Bayern as interim coach Hansi Flick oversaw a performance with few highlights on his debut.
But Lewandowski's 69th-minute opener and Perisic's strike in the 89th, a minute after he came on as a substitute, were enough for the Bavarian powerhouse to reach the last 16. With two games remaining, Bayern tops Group B on 12 points, eight ahead of last season's finalist Tottenham, which was playing at Red Star Belgrade later.
Kovac was fired on Sunday, one day after the seven-time defending German champion slumped to its heaviest Bundesliga defeat in more than 10 years with a 5-1 loss at Eintracht Frankfurt.
Against Olympiakos, it was a cautious game from Bayern with little fluid play. The home side dominated possession but displayed little urgency or imagination going forward. While Bayern racked up attempts after Leon Goretzka first tried his luck from distance, Olympiakos 'keeper José Sá proved equal to the few that were on target.
Sá produced excellent saves to deny Kingsley Coman, then Thomas Müller before Benjamin Pavard was denied by the post before the break.
Coman tested Sá again after the break, before Lewandowski finally made the breakthrough with Bayern's 20th attempt of the game.
Coman fired the ball in from the right and the Polish striker deflected it in with his right boot for his sixth goal in four Champions League games.
Perisic had an easy finish to seal the win after some good play from Coman and Corentin Tolisso in the build-up.
