Whatever your opinion on Gabby, I think the whole situation (even more so N'Zogbia) really highlights that something needs to be done about footballers contracts. The fact that a player could sign a five year contract and then essentially have a terrible attitude, let their fitness go, be generally disruptive etc.., but still collect their full pay for the whole five years just isn't healthy for the game.
They really need to be regulations on minimum standards in contracts. Particularly to protect smaller clubs. (I realise this is never going to happen with player power the way it is)
