The agent of Emanuele Giaccherini expects Sunderland to demand top price this summer.
The winger has been on-loan at Bologna this season.
Fulvio Valcareggi said: “He will be going into the last year of his contract and I think that makes it more affordable.
"But there will still need to be some negotiations with Sunderland. They do not have economic problems and therefore do not give gifts."
