Juve chief Alessio Secco confirmed their interest in Candreva yesterday.
Spinelli said: “I have asked the Bianconeri for players in exchange because I cannot deprive myself of such a talent without having anything in return.
“If they give me someone like Giovinco or even De Ceglie or another player who can help my Coach then I can also facilitate Antonio who wants to go to a big club.
“Giovinco is what we need, but Bologna's Marcelo Zalayeta would also do fine as Juve own half of his contract. We need a centre-forward or a second striker. In the meeting with Genoa about Candreva I will instead ask for Zapater in exchange.”
