Former Livorni coach Fernando Orsi says AC Milan fans deserve to be upset if Sandro Tonali is sold.
Newcastle United are in advanced talks to close a deal for the Italy midfielder.
And after Paolo Maldini's sacking as technical director a fortnight ago, Orsi says the Rossoneri support should be angry.
He told Sky Italia: "Tonali should have been Milan's banner for the next few years.
"If I were a Rossoneri fan I wouldn't take his sale well. His departure is after that of Maldini. They are two heavy blows for the Milan fans."
