Juventus management are determined not to lose Daniele Rugani.
The defender is regarded highly inside Juve, but has struggled for minutes this season.
Tuttosport says Juve GM Beppe Marotta has rejected a €22 million bid from Napoli for Rugani.
Enquiries from Manchester United and Liverpool have also been dismissed.
Sampdoria, meanwhile, are favourites to take Rugani on a six-month loan from January.
