Atletico Madrid forward Joao Felix was sent off as the LaLiga champions were held to a 0-0 draw at home to Athletic Bilbao on Saturday.
Felix, Atletico's record signing, was shown a yellow card for striking Unai Vencedor in the 78th minute and the Portuguese reacted to the decision by shouting at the referee, who instantly produced a second card and sent him off.
Felix had only been on the pitch for 18 minutes when he was dismissed, with Spanish media reporting the Portuguese said "Are you crazy?" to match official Jesus Gil Manzano after being penalised for tangling with Vencedor as they challenged for the ball.
Diego Simeone's side are top of the standings with 11 points from five games while Athletic, who are also unbeaten, have nine.
