The £40 million man's contribution for the Gunners has been criticised in the wake of a poor performance in their 5-1 hammering at the hands of Liverpool but the Spaniard does not feel that a switch from Spain, where he was used to having a winter break, is to blame for the blip.

"The problem Mesut has is, when he's on form, everyone can play off him and, when his form drops a bit, he is missed.
"You have to make him feel appreciated and give him the confidence he needs. He's a key player for us and let's hope that he gets back on form. We all have great confidence in him."
With reigning champions Manchester United up next on Wednesday, Cazorla is keen to put the Liverpool defeat behind them by winning at the Emirates Stadium.
The midfielder added: "The good thing about football is there's always another game and the sooner the better.
"On top of that, we have a one against a great rival like Man Utd, who are Premier League champions. It will be very difficult, of course, but what better chance to turn things around than by beating United in front of the home crowd?"
