Hartlepool have announced they will not sign convicted rapist Ched Evans after boss Ronnie Moore expressed an interest.
Arsenal manager Arsene Wenger insists he will only spend money in January on the right player.
Both players have been granted permission by the Florence-based club to undergo a medical with Napoli before completing permanent transfers to the azzurri outfit.
A statement from Fiorentina read: "After the negotiations undertaken by ACF Fiorentina and SCC Napoli, our players Valon Behrami and Alessandro Gamberini have been authorised to undergo medicals with Napoli."
Behrami, a Swiss midfielder, joined Fiorentina in 2005 from Bologna.
The 27-year-old is set to sign a three-year deal with the Partenopei side.
Italian central defender Gamberini, meanwhile, is expected to put pen to paper on a contract that will keep him tied to Napoli until June 2016.
