Kalidou Koulibaly is reportedly unhappy at Chelsea and has spoken to Massimiliano Allegri over a move to Juventus this summer.
The Senegalese international joined the Blues from Napoli for £33.6 million but has endured a frustrating first season in the Premier League.
Chelsea are set for a clearout this summer in an attempt to cut down on their big squad after an underwhelming campaign which sees them currently sit 11th in the league.
According to La Gazzetta dello Sport, Juventus are working on a deal to bring Koulibaly back to Serie A after year away from Italy's top flight.
