The two teams meet this weekend.
Arteta said: "All positive and incredible things.
"First his work rate, the amount of hours that he puts in, the details, and the people around him to support, help and always evolve his ideas, and then who he is as a person. And that's all really well respected by everybody that works alongside him.
"He has a unique way of training, of putting things together, and making a team play the way that every single player believes in what they have to do, and even if he's difficult and challenging they still do it."
