Chelsea have confirmed the transfer of Kalidou Koulibaly from Napoli. The experienced centre-back will be part of manager Thomas Tuchel’s rebuilt defence after the summer departures of Antonio Rudiger and Andreas Christensen.

Koulibaly, 31, played for Napoli since 2014 and made 26 Champions League appearances, making him an ideal fit for a Blues side which will be aiming for a deep run in the competition next season.

Chelsea may consider further reinforcing their back-line before the end of the summer, with Paris Saint-Germain star Presnel Kimpembe and Matthijs de Ligt having been heavily linked over the past month.

Chelsea will pay £34 million ($41m), including add-ons, to complete the deal for the experienced Napoli defender.

The Senegal international, who captained his country to Africa Cup of Nations glory back in February, has signed a four-year contract in west London through to the summer of 2026.

He will earn an annual salary of around £8.5m ($10m) during his time at Stamford Bridge.
