Really surprised no one has mentioned Cheike Tiote to be frank.
The Newcastle squad has a lot of players who have great individual skill for the game, but they have been mismanaged time after time...
Mike Ashley doesn't have the clubs interests at heart and that has a lot to do with their downfall... Apart from Tiote, there is any of Cisse, Shelvey, Townsend, Colback, Bigirimana, and Coloccini who could all potentially make it at least at top-half Prem sides (although not at our clubs level).
Also from Villa, our very own Micah? Agbonlahor is extremely underrated also.
