Speaking ahead of Saturday's game at Aston Villa, Arteta said: "[Rice is] extremely intelligent to read situations, to break up play, to win duels - crucial duels in certain areas of the pitch that allow us to counter and progress in really dangerous situations.
"He is really humble, funny, really hardworking. He is extremely committed in everything he wants to do. He wants to win everything that he does. Really easy going, he's integrated in the team in a really positive way.
"I was really positive about it because when I spoke to him, he mentioned to me many times from day one, 'I just want to play for Arsenal and I want to play with you' and he maintained his word to the last moment and we were good enough to acquire him."
