Napoli’s Kalidou Koulibaly is apparently Chelsea’s top transfer target this summer.
According to TuttoMercatoWeb, the London club head coach Antonio Conte is a long-term admirer of the defender and tried to sign him last year.
Koulibaly has made 29 appearances during this season.
Koulibaly began his professional club career with French side Metz in 2010, before moving to Belgian club Genk in 2012. He joined Italian side Napoli in 2014, where he soon established himself as one of the best defenders in Italy.
