After their shock defeat to Middlesbrough yesterday, Arsenal boss Arsene Wenger admits he has injury problems going into this weekend's big match against Chelsea.

"The missing players have handicapped us a little but it doesn't mean we should give away a penalty after five minutes," said Wenger.

"Flamini could be back for Chelsea, Van Persie might be back in the squad. Fabregas we don't know. Diaby is also possible but I have faith in the players who are there."
