The agent of Alberto Gilardino insists the striker is staying with Fiorentina.
There have been reports of big bids from clubs around the continent following the Viola's failure to qualify for Europe.
"We have not received any official proposal from Napoli. In any case, Gilardino does not want to leave Fiorentina and the club thinks it improbable they'd agree to a sale," Giuseppe Bonetto told Violanews.
"Not only does Alberto not want to quit Florence, but as far as I can tell Fiorentina do not wish to release him either.
"Besides, Pantaleo Corvino would never strengthen a direct rival for places."
