The agent of David Trezeguet says the Hercules striker is wanted back in Serie A.
Trezeguet only moved to Hercules in the summer from Juventus.
"Fiorentina and Napoli are looking at him, and I would also say Roma too," his representative Antonio Caliendo told Tuttomercatoweb.com.
Caliendo also refused to rule out a return to former club Juventus, adding: "We will have to see what happens. I can see some changes, but they are not an experimental club."
