Emery's Villa are third in the Premier League, four points behind leaders Arsenal, who they host today.
Arteta said of his fellow Basque tactician: "I've followed him and seen what he's done for every team, which is remarkable.
"He always improves players, teams and clubs. He's a manager I always admire. He's done it in many countries and at different levels, so I'm very happy for him.
"Tactically, they're very well set up and they're brave to play from the back. They're a constant threat and then you have the atmosphere and intensity of them being at home.
"They fully merit where they are."
