The Spaniard moved to the Emirates Stadium from Malaga in the summer at a time when the England international had missed a year of action through injury.
However, having played together since October, Cazorla has no doubts that Wilshere has a spectacular future ahead of him.
"He adds something extra and I'm gradually getting to know his style of play better," Cazorla told Arsenal Player. "His way of playing complements my own; in fact, we play in similar positions and that makes it easier for us to establish a greater understanding every day.
"As I've said, he adds that little bit more that we need in many of our games. His return from injury was a great plus for the club and we all hope he can maintain the level he's at because he's very good.
"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."
Arsenal travel to Tottenham Hotspur on Sunday.
