Kalidou Koulibaly: Chelsea sign Senegal defender from Napoli on four-year deal

Chelsea have signed centre-back Kalidou Koulibaly on a four-year deal from Serie A side Napoli

The Senegal international, 31, joined Napoli from Genk in 2014 and made 317 appearances for the Italian side, Qazet.az reports.

His arrival at Stamford Bridge follows the departures of defenders Antonio Rudiger to Real Madrid and Andreas Christensen to Barcelona, both on free transfers.

"I'm very happy to be here with this team at Chelsea," said Koulibaly.

"It's a big team in the world and my dream was always to play in the Premier League. Chelsea came first to get me in 2016 but we didn't make it. Now when they came to me I accepted it because they really wanted me to come to the Premier League to play for them.

"When I spoke to my good friends Edou [Mendy] and Jorginho they made my choice easier."
