He may well be able to do more going forward, but it's obvious to me that we needed far more dicipline in midfield than the gung ho set up of last year. When song goes forward arteta sits, and the other way around. We needed it. It may not be pretty, but where denilson and to a certain extent, jack and cesc failed, has been bettered from a team point of view. When you play with attacking fullbacks, you need your midfield to be clever enough, and that's what we have. That said, all three look knackered from playing every sodding match. Agree arshavin would be good in the hole role. We don't need to replace anyone though. Which was the OP's point. A point which i think is as devoid of intellegence as, for instance, selling RVP for being useless.
