But also every transfer window for past 2 years its reported as surely leaving, but he allways stayed. And with Chiellini at his last legs, Rugani and the club might be fine with him to remain emergency depth (and hope he might have a Bonucci like growth).
If he had real tempting market value, he would been gone already. Otherwise its just been pointless enquries by Chelsea, Arsenal, Watford or whoever that go nowhere. Or loan request (Arsenal). No Italian club will pay tempting enough figure for us to be in a hurry to sell.
Only tempting speculation was few years ago when Sarris Napoli wanted him, but even then that might been media invention.
