Mourinho has publicly stated that Fella is a crucial squaddie and with the amount of game time he gets, Fella has every right to start thinking he is indispensable. Tbf, he has played alright so far this season, albeit against mid-table dross but isn't that the whole point of having a good squad? So that you can play your dross against their dross and still win?
Anyway, he's 30 and a jobber, so if he doesn't want to sign a new contract on our terms, then let him move on with our best wishes. If he can get more elsewhere, good luck to the Fella
