Fiorentina are eyeing Sunderland midfielder Emanuele Giaccherini.
Sunderland boss Gus Poyet admits the player is unhappy.
"He's not happy for sure, but he's a professional. He trains more than anybody and he wants to run more than anyone else," manager Poyet told the Sunderland Echo.
"I'm sure he's desperate to have a chance. I think he's deserved more minutes in the team, but, for some reason, I can't play him. It's more me than him. It's like the situation was with Fabio Borini.
"We're trying to do things and there's players in certain positions that I really like and I can't use him in the manner I want to."
