Chelsea complete signing of Napoli defender Kalidou Koulibaly

31-year-old Kalidou Koulibaly has joined for a reported fee of £34million and has agreed a four-year contract.

Chelsea has signed centre-back Kalidou Koulibaly from Napoli for a reported fee of around £34million.

The 31-year-old becomes the club’s second summer acquisition following their move for England forward Raheem Sterling from Manchester City.

Koulibaly has signed a four-year contract at Stamford Bridge and will boost defensive options following the departures of Antonio Rudiger and Andreas Christensen.

Koulibaly told his new club’s official website:

“I’m very happy to be here with this team at Chelsea. It’s a big team in the world, and my dream was always to play in the Premier League.

“Chelsea first came to get me in 2016, but we didn’t quite make it. I accepted it when they came to me because they wanted me to come to the Premier League to play for them.”
