Chelsea FC manager Thomas Tuchel has blamed himself for their Wednesday night defeat at the hands of Arsenal.
The German in his post-match interview admitted that the many changes he made in the tie affected their rhythm and that they were wasteful in front of goal.
"The first half was OK, it was enough to lead 3-0 but we were 1-0 down because we forgot to score at the other end and then scored an own goal practically, I don't know how Arsenal would've scored if we didn't give it to them ourselves.
"We were not sharp enough, not the same energy as usual. We are responsible, I am responsible, we are all in this together so it was not enough to win the game,” Tuchel said.
The manager further admitted that he wants happy with how they wasted chances with the loss being a lesson for his side.
"Bit angry that we had so many changes, that's on me, not so happy in the end with the line-up, but I didn't know what would happen, I didn't feel us today like I normally do and we can't expect to win games if we're not 100% in games. We didn't have a shot for almost the whole second half, then we had a big one, maybe we deserved this today, we learn something.
"I'm not happy with what I saw, I have my responsibility because I picked the line-up, but the performance was the performance," he added.
Chelsea will next face Leicester City in the FA Cup final on Saturday.
