Samir Nasri cannot explain how Manchester City lost their FA Cup quarterfinal tie against Wigan Athletic.
Nasri is grateful they do not have time to dwell on the setback with tomorrow's Champions League clash at Barcelona looming.
Asked how he felt about the Wigan result, Nasri said: "Hungover. It was a bad performance, we didn't play well.
"The big disappointment is that it is twice now that Wigan have beaten us in the FA Cup. It is really difficult to accept.
"It is like - the FA Cup, they gave it us on a plate and we refused to take it.
"I really don't know. I cannot find the words because I am really disappointed. Thank God we play a big game on Wednesday. It is the best way to forget this game and be focused on the next one.
"At training we are going to think Barcelona and try to think positive and get a result there."
