Arturo Vidal was sent off by referee Viktor Kassai in the second half of Bayern Munich's Champions League defeat to Real Madrid.
Bayern won the game 2-1 in 90 minutes, but that was only enough to force extra-time, with Madrid going on to score three more goals with the man advantage.
Vidal got to the ball before Madrid's Asensio, but Kassai did not see it that way and booked him for the second time in the game, leaving Bayern a man down in the final stages of normal time.
Claudio Bravo, the former Barcelona goalkeeper now at Manchester City and a team-mate of Vidal with Chile, was quick to complain on Twitter.
