I think his input attacking wise has been minimal but he's very disciplined at what he does, and I do think he provides bit of solidarity in midfield. I guess that was drilled into him at Everton.
Maybe it's not worth expecting him to attempt more ambitious passes, given it's actually Ramsey who looks like being the direct replacement for Cesc, although I believe he should make way for Wilshere when he's back.
I prefer the idea of Song and Arteta doing the donkey work, going unoticed in games, whilst Ramsey/Wilshere do their own thing.
During the Cesc days, I always felt the midfield was lopsided towards the attack, and that was both a strength and a weakness to our game. Now we have a basis more suited to the Prem IMO, although possibly not for the CL as the goals haven't exactly been flowing in Europe.
