The Viola had been set to sign a contract extension with their captain when he suddenly pulled out of talks to think things over.
That may well be due to reported interest from the likes of Inter and Arsenal.
"I repeat that we have no intention of losing the player, especially as we have never received any offers for him," director of sport Pantaleo Corvino told Sky Sport Italia.
"We believed in his qualities right from when he was a kid and because we trust in his future, we offered a five-year contract extension.
"His agent has made certain requests of an economic nature over the last few days."
