It’s reported Napoli offered Mirko Valdifiori plus €7m cash for Torino defender Nikola Maksimovic.
The Partenopei had already been heavily linked with the 24-year-old over the summer and were in a bidding war with Milan.
According to Tuttosport, Toro value the Serbian centre-back at over €20m.
Napoli hope to sweeten the deal by including ex-Empoli midfielder Valdifiori along with a €7m cash sum.
Maksimovic only just extended his contract to June 2020, but on the other hand he has been out of action with a fractured metatarsal since September.
