Napoli will complete the transfer of Marco Donadel at some point on Tuesday, Sky Sport Italia claim.
The former Under-21 international will be out of contract at Fiorentina at the end of this month and he is available on a Bosman.
The 28-year-old's agent Davide Lippi will hold talks with Napoli sporting director Riccardo Bigon to finalise terms.
Donadel, formerly of Milan, Lecce, Parma and Sampdoria, will reportedly put pen to paper on a four-year deal.
