Mari is delighted to now be playing for Arteta.
"One of those legends that we have with us now is Mikel. He was a very important player for Arsenal and now this is a new project for him as coach, but I think he's going to repeat what he achieved when he was a player.
"Personally I look up to him and the career he had at Arsenal. That's what I've been working for all these years.
"I'd love to be at Arsenal for a long time and I hope to give the Gunners some victories to celebrate again."
