Rook
Player Valuation: £80m
Honestly - he'd be dreadful, as he has been for United. He had a few good games for us as a central mid, yes, no denying that, but he's about as mobile as a statue and also what @Rook said.
Some sort of second striker, or even an actual striker though - it honestly might work - he's good enough at all those things a big target man is, but is somehow a midfielder. Only downside is his lack of pace, but if used correctly...
Fellani is a bit of strange brew. Been watching this team for 12 years now and he 1st player here who never was scared of top opposition. When he's at his best he's devouring everything in the middle of the pitch for good or bad (one on hand he'll blow up teams like man city on the other hand he'll take all of Arteta's touches too). So he can be an absolute terror if you are playing a side who has to sit back. However he's a kind of a liablity if you are the side in always with possession and you need that goal to kill off a Stoke or a WBA. He would have been nice to have against the RS the other night, against Swansea though, probably not.
He would solve a lot problems that say Sunderland and LC are having right now. For us (and not I think that we are world beaters), if goal is Europe/4th, I think he'd have to be a situtational player even though he's probably too good to be a situtational player for us if you could understand that sentence.
