IF we get Fellaini our aerial game will be so dominate. Rio, Vidic and then Fellaini. Teams won't be able to handle that. Plus, we do need some height in midfield and the third of the pitch.
You can't win the big competitions relying on an aerial game though. I don't mind signing Fellaini but I don't think that Everton want to sell and they won't sell for less than the expired release clause. For that sort of money there must be plenty of players that we could buy that would improve us more.
As a lot of Everton fans will tell you, Fellaini is unplayable a few games a season, the rest of the time not so much. We need to add real quality not depth to our squad. We never have problems bringing in backups, we need first team players who will make us a much stronger team. To me Fellaini doesn't do that.
