Napoli president Aurelio De Laurentiis has reportedly informed manager Carlo Ancelotti that centre-back Kalidou Koulibaly will not be leaving the club this summer.
Koulibaly is allegedly a man in demand ahead of the new domestic campaign, with Manchester United and Chelsea previously linked with the defender's signature.
According to Premium Sport, however, De Laurentiis has ruled out the Senegalese international's exit from Napoli by telling Ancelotti that no offers will be considered for the centre-back in the current transfer window.
Koulibaly, who signed for Napoli from Genk in 2014, agreed a contract extension in 2016 that runs until 2021.
The 26-year-old scored five goals in 43 appearances last term.
