Mainz suffered a 4-0 thrashing at the hands of Bayern Munich in the second round of the DFB-Pokal on Wednesday. Jamal Musiala scored a hattrick, but the game didn't end without drama.
Videos that have surfaced online show how Michael Olise initially walks past the Mainz fans at the sideline during warm-up and then seemingly shows them the middle finger. Before that, some home fans can be heard insulting and abusing the French winger.
