The Italian coach knows that Kalidou Koulibaly is on more than one European club's agenda. The full-back's worth is recognised across the continent and has already rejected some offers in recent weeks.
According to the information published by 'Bitbol', United offered 95 million euros to take the defender to Old Trafford. Koulibaly responded with a resounding 'no'.
If Raphael Varane leaves the Bernabéu, Madrid could put an offer in for the full-back, which Carlo Ancelotti spoke about in a press conference.
"Napoli are not obliged to sell. Koulibaly and Allan will not move. If they sell them, I'll chain myself in front of the sports centre," said the Italian.
