I don't have too much issue with Fabregas' contribution per say.
My opinion is that the way we play gets the best out of Fabregas but reduces the effectiveness of our other forward players. Then again, it's a fair point that Arshavin, Nasri and Walcott aren't on the same level as Pires, Henry and Bergkamp so it's understandable that Arsene relies on Fabregas like he does, particularly when RvP is out. . Also, I feel that when Fabregas plays in his current role, he doesn't influence the game like he used to and can be marked out by organised defences. This was never the case when he was a central midfielder where he routinely dominated games against better teams, even when we lost. Allowing Fabregas to worry about the creative side of the game (along with Wilshere) and buying a proper goal scorer to help van Persie/Arshavn/Nasri would bring us more stability.
That would also make Song's life a lot easier.
