The midfielder, who has impressed since his £15m summer arrival from Malaga, has likened Arsene Wenger's tactics to those employed by many Spanish sides.
"For me it is important to go out onto the pitch and be comfortable and that has been the case from the first game," said the 28-year-old.
"I have always been at ease on the pitch. In my case too, you do not notice much difference between Arsenal and playing in Spain, because we are also a side who like to play with the ball.
"The boss has a philosophy of playing football, it is always trying to find attacking football, of having the ball.
"Because of the characteristics of the players we have, it is what comes easiest to us."
