Agreed he has looked very good so far except against Chelsea to be fair where you could see why players like Mata and Hazard are rated more highly.
Rated more highly by whom? Cazorla easily gets more game time for Spain compared to Mata. In fact, I am pretty sure Mata did not even make it into Spain's latest squad. Cazorla was not at his best against Chelsea because they marked him well. Mata and Hazard had more freedom. Even then they hardly did anything that was amazing in open play.
