The pair are combining well in Arsenal's midfield this season.
Cazorla told arsenal.com: “I didn’t know much about him when I came to the Club because he hasn’t been around for very long. He surprised me because he is such a complete footballer.
“He’s young and has a spectacular future ahead of him and he’s also got a lot of room to mature and develop. I have no doubt that he’s going to be even more important here in the future.”
