Napoli wants to hold on to its Senegalese defensive superstar.
Manchester United are determined to strengthen their defense and have had a bid for Napoli defender Kalidou Koulibaly turned down by the Italian club.
The 27-year-old was the subject of a bid of €90m from Manchester United and is reported to be Red Devils' No. 1 priority with other interested clubs including Real Madrid, Barcelona, Manchester City and Bayern Munich.
According to reports in Football Italia, the Senegal international, who has just been nominated for the BBC African Player of the Year Award, is admired by Manchester United boss Jose Mourinho who is keen to sign the center back to solve his defensive woes.
Koulibaly has been ever present at the heart of the Napoli defense this season playing every Serie A game with impressive displays and even chipping in with an assist for his team.
The defender has only recently signed a new contract, tying him to the club until June 2023 and the price tag, if he were to leave, could be well over €100m in the current market, forcing United to offload some players to balance the books.
