Tuchel said, "Tough work, tough game against a very strong opponent with a fantastic crowd today. The atmosphere was amazing for the home team.
"We stepped up after 1-0 down, very good reaction. In general a very good team effort. We hit the post.
"I think the referee (Glenn Nyberg) 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 quarter-final is not enough for him to give a penalty. He admitted he saw the mistake the player made.
"It was a goal kick off, 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.
"We were relentless and kept on believing and kept fighting. Everything is open now."
