What gives you the idea that he's particularly 'popular' with his teammates? He was given the role mainly because of his seniority, partly because he's been a consistent performer for a few years and partly because of the lack of obvious choices. But it's irrelevant as we know - Wenger kept Vermaelen out the team and so if he feels Arteta is no longer the best option within the squad for that DM role then he won't be starting.
