The French winger, surrounded by three Hertha players, headed in from close range in the 98th minute, handing victory to Bayern who had dominated the encounter but somehow failed to win in normal time.
Hertha took a third-minute lead with their first effort on goal through Maximilian Mittelstadt but it was all Bayern after that as the visitors bossed the ball with 75 percent possession.

Serge Gnabry fired in the equaliser four minutes later and then scored again four minutes after the break to put the Bayern ahead.
Yet a blunder by defender Mats Hummels, who headed the ball into the path of substitute Davie Selke, allowed Hertha to equalise with only their second shot on goal.
Coman then came to the rescue in the first half of extra time to save Bayern's blushes.
