Chelsea are in talks over a deal to sign the Napoli centre-back Kalidou Koulibaly as Thomas Tuchel pushes to fix his side’s defensive crisis before the start of the Premier League season.

The departures of Andreas Christensen and Antonio Rüdiger have left a huge hole in Tuchel’s defence and Chelsea’s head coach would like to sign at least two centre-backs. Personal terms have been agreed with Nathan Aké, who will cost at least £40m, and the spending will not stop if the Manchester City centre-back completes a return to Stamford Bridge.
