Quagliarella has been linked with Genoa in recent days.
"There is absolutely nothing in the reports," Beppe Bozzo told Tutto Juve. "All of these stories are unfounded, they don't belong in the air or on the ground.
"Fabio is very happy to be at Juventus and he wants to stay in Bianconero.
"I can categorically rule out a January transfer. Quagliarella is going nowhere in January and he'll definitely stay at Juve."
