Torino great Ciccio Graziani has called for Nicolas Nkoulou to be banned.

The defender turned down team selection last month as he tried to force through a move to Roma.

“Nkoulou deserves a very long ban, as he was unprofessional and unreliable, both terrible things," Graziani told Toronews and Tuttosport.

“By signing a contract, that player has the right to receive his salary, but also the duty to step on to the pitch when called. UEFA and FIFA ought to intervene as well.

“The correct punishment would be to suspend him for at least four years without pay or the chance to set foot on the field."
