He's become a parody. Everyones saying its a travesty he's gone yet he's currently behind Capoue, Bentaleb, Dembele, and now Stamboulli. Not to mention we have youth players we can bring through.
Yeah he is behind them, but everyone probably thinks he deserves to be ahead of them (well Capoue/Bentaleb definitely). I personally do not understand why we are selling him, when he isn't injured and playing regularly he is one of the best defensive midfielder around.
