Chelsea haven't dropped their pursuit of Napoli defender Kalidou Koulibaly.

Koulibaly was reportedly on Chelsea's radar last summer and the Premier League champions are said to be interested in a move for the Napoli centre-back again this time around.

Calciomercato.com says that Antonio Conte's side are waiting in the wings with a €60million (£52.2m) move for the 25-year-old Senegalese international.

With Kurt Zouma linked with a loan move away from Stamford Bridge and John Terry's departure, Conte appears to be making defensive reinforcements one of his top priorities.
