Arteta says the ex-Malaga man is a regular matchwinner for Arsène Wenger's team.
"I think he's been outstanding," Arteta told arsenal.com. "He's played almost every game and is probably the only one [to have done that].
"The way he plays, he takes a lot of knocks and plays a demanding game physically as well. To adapt to the Premier League in his first year and do what he's doing, I think we have to clap him. He deserves that.
"He seems to be comfortable when he plays off the left. He's got a lot of freedom and he causes problems to the other teams because we can use the extra man in midfield.
"I think he's a player that can make the difference with his ability. I think Jack's another one of them that has something special that can decide a game or can unlock a door when the game is really tight, as he did today with the ball to Nacho. For us, they are very important players.
"I think he [Cazorla] needed a few goals like that. He helped the team to earn the points today. He was outstanding - his overall play as well. He was involved in many areas of the pitch today and he's a top player."
