I agree - his biggest problem is his attitude, and it is Rosicky's work ethic and attitude that has kept him at the top. Arshavin is a very similar player to Cazorla in many ways, but it's the laziness and non-existent back-tracking that has been the real problem for him on the wing.
This doesn't really affect Cazorla when he starts on the wing, as it is often when Rosicky starts in the midfield, allowing them to switch positions during games (just like Benayoun and Rosicky did last season), and it often ends up with Rosicky tracking back.
