Cazorla is enjoying playing alongside England international Wilshere in the heart of Arsenal's midfield.
"Jack is a vital player," he said. "He adds something extra to the team and I'm gradually getting to know his style of play better.
"His way of playing complements my own - in fact, we play in similar positions and so that makes it easier for us to establish a greater understanding every day. He adds that little bit more that we need in many of our games.
"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.
"Certainly, he's highly valued in England for being a complete player and I have no doubts that he's going to be even more important here in the future."
