People that thought we could replace Cesc with a like for like midfielder (in terms of talent and quality) were kidding themselves. Sorry to say. The money may be there, but no way we're willing to spend that much on one player.
I'd have preferred M'Vila too, but Montolivo is good as well. Arteta I'm more skeptical about, even if he IS a good player (I preferred him over Arshavin back in the day. I was mocked).
