Napoli President Aurelio De Laurentiis says Juventus won't be getting a discount on Fabio Quagliarella this summer.
Juventus have an option to buy the 27-year-old striker once his loan deal expires in Turin at the end of this season.
Quagliarella was Juventus' top scorer before suffering a serious knee injury in January.
There have been suggestions that Juventus will use this to haggle down Quagliarella's asking price.
"I won't gift Quagliarella to Juve," De Laurentiis said.
"Juventus general manager Beppe Marotta signed a contract. The option price is already fixed and it will remain that way.
"I am not stupid. I wouldn't make a gift of Quagliarella," he concluded.
