This Joao Felix red card vs Athletic Club was a very controversial incident, with referee Jesus Gil Manzano effectively issuing him two yellow cards in a matter of seconds. Felix felt hard done by the first yellow card and appeared to indicate to Manzano that he (the referee) was crazy, and was promptly given a second yellow for insulting the referee and sent off!
