I think this is a big gamble by both Arteta and Arsenal. First Arteta has never managed a club before and I would love to to see how he handles the egos in the dressing room. Yes he has promise but Arsenal are getting inexperience. On the other hand if Arteta fails at Arsenal it would be a blow to his career as a lot would think that the hype was all for nothing. So it was also a risk for him coming to Arsenal instead of a smaller club.
