Chelsea are closing in on the €40million (£33.7m) signing of Kalidou Koulibaly from Napoli, football.london understands. The Blues are expected to make the 31-year-old their first defensive signing of the summer transfer window.
As football.london reported on Tuesday afternoon, Thomas Tuchel recently approved making a move for Koulibaly, who has been on the club's radar for a number of years now. The Senegal international has less than 12 months remaining on his contract at Napoli, who are seemingly open to selling their star defender.
Koulibaly has been at Napoli since the summer of 2014 after he signed from Belgian club Genk for around £6.5m. Since then, his performances in the south of Italy have made him one of European football's most sought-after defensive players.
