The 26-year-old centre-back has made 119 appearances for Napoli since his debut back in 2014 & his outstanding performances in Italy are understood to have caught the attention of both Chelsea & Liverpool.

It is believed Napoli would have considered an offer of around £52million for Koulibaly in the summer but the Senegal international chose to stay on at the Stadio San Paolo to win silverware.

Antonio Conte is an avid admirer of Koulibaly & has expressed a strong interest in the defender during his 2 summers at Chelsea.

Back in June, Satin told Mondo Napoli: 'Koulibaly? The transfer market is long as it will be open until August 31, something might happen before then.

Chelsea ultimately settled on a £29m deal for Antonio Rudiger, with the Germany defender signing a 5-year deal with the Premier League champions last month.
