Speaking after the game, Tuchel said to TNT Sports: "I think the referee did not have the courage to give a deserved penalty today in a bit of a crazy and awkward situation.
“He admitted on the pitch that he saw the situation and that [for a] quarter-final [the incident] is not enough for him to give a penalty, for a kid’s mistake. He admitted he saw the mistake the player made.
“It was a goal kick, the goalkeeper passed to a central defender and one touched the ball with the hand because he thought it was not in game. But it was in game and the referee admitted it was in game and was handball. Very frustrating.”
