Torino defender Nikola Maksimovic is on Chelsea's radar.
The Serbia international is well known to Chelsea boss Antonio Conte, who is eager to add a new centre-half to his squad.
Italian transfer expert Gianluca di Marzio reports Conte has Maksimovic on his agenda as an alternative to Napoli defender Kalidou Koulibaly.
Chelsea offered €40 million for Koulibaly yesterday.
If Napoli refuse to do business, Conte will turn to Maksimovic.
