The agent of Napoli defender Kalidou Koulibaly cannot rule out a summer move to Chelsea.

Antonio Conte tried to sign the centre-half last year and is keen to bolster his backline again.

And the defender's agent has added fuel to the fire the Napoli man could complete a transfer away from the club before the summer deadline falls.

"Koulibaly? The transfer market is long as it will be open until August 31, something might happen before then," Bruno Satin told Mondo Napoli.

"Chelsea? They are a world class team that many players would like to join but I don't want to talk about this now."
