In the third round of the UEFA Champions League, Barcelona faced Olympiacos at home. In this game, the visiting team's Herze was shown a yellow card in the 57th minute for hitting Casado in the face with his wave. Two yellows turned into one red and he was sent off. Regarding the decision of Swiss referee Schneider, "Marca" referee expert Pérez Burrull expressed his opinion.

Bruel said: "The Swiss referee made a serious mistake, because in this confrontation with Casado, he absolutely should not have shown a yellow card to the players of the Greek team. In fact, the first yellow card was avoidable."
