Assuming we keep the likes of Barton, Tiote and Enrique. I would say we need a new striker, probably two would be required, cover for the wings and cover at full back. Would like to see us sign a player like Kranjcar for wing cover and maybe the utility man Pardew speaks of could be Jamie O'Hara, not a bad player and can cover three positions. Once Ben Arfa is back fit I would imagine he would play off the front in a 4-4-1-1 or 4-2-3-1 formation as the attacking mid/free role is his best position, that is why I think we need a winger. Being linked with Matt Jarvis, looks a canny little player to me. Genuine wide mean, two footed and has a bit of pace as well, end ball looks far better than Jonas' as well.
Problem is, I think one of the first three mentioned will leave, so we will need to replace them.
Can't say I agree with dropping Nolan like, he does seem to be a bit of a passenger at times, but we look unorganised, uinterested and generally just a complete shambles when he doesn't play, his leadership qualities are outstanding and he weighs in with important goals. Shame he's such a fat bugger, I really don't get how he is so unfit, he's a pro footballer FFS!
