The head coach of Roma, Claudio Ranieri, was dissatisfied with the referee's work during the first playoff match of the Europa League against Porto.
— I cannot understand how a person like Mr. Rosetti would appoint a referee who has seen nine draws in 22 European matches by the visiting teams. In other matches, the home teams won. You are a decent person, but do you not know this? The atmosphere is tense, the fans are pressuring, and the referee succumbs to their pressure. I don't understand why. He walked around threatening players with cards. I think he was waiting for something to happen in our penalty area so that he could award a penalty. That’s why my footballers were so furious,— said Claudio Ranieri.
It should be noted that the main referee of the match, German Tobias Stieler, showed eight cards to Roma players, including a red card to Cristante, and also dismissed a member of Ranieri's staff.
