Chelsea are closing on a deal for Napoli defender Kalidou Koulibaly.

The Blues have met with Koulibaly's agent Fali Ramadani to agree on the terms for the defender's move to London.

A fee in the region of €40m is now being discussed.

French journalist Fabrice Hawkins claims that Koulibaly is "very close" to signing for Thomas Tuchel's team.

The Senegalese international "should commit" to a three-year deal.
