Wenger: 'We are a bit jaded physically'

"We are a bit jaded physically, and we did not make the most of our opportunities. The final ball was not good enough, even though we battled well to the end. The spirit was excellent, but we didn't create enough. The conditions were not good, but they were the same for everyone.

"We are not guaranteed to be in the top four and we want to be in there, we have a difficult programme and must not fail to be in that top four.

"It is very frustrating not being able to make the most of our chances when we play well. This month, mentally, has been very hard for us. We lost at Blackburn in the last minute, we lost to Eindhoven late in the game and the same against Everton as well as losing a late goal to Chelsea in the Carling Cup Final. What we are missing is the maturity to deal with that.

"Walcott's season is over. He will have surgery on Tuesday. The medical advice is to do it now. He was doing well until he damaged his shoulder, now he is only 50% of what he was before. You can see that now. He was on for only 10 minutes and his shoulder popped out, you cannot play football like that."
