"He's a very good signing, and he's proving it," Cazorla told Arsenal Player.
"Nacho is a footballer I really enjoy watching and playing with. I spent last season with him at Malaga and he was a vital player for the team. He's adapted to the Premier League very well. What's more, our style of play suits him because he's someone with a lot of movement.
"I think Arsenal have really got it right with the transfer. I'm very happy because he's a great mate."
