Manchester United and Bayern Munich are among clubs tracking Napoli centre-back Kalidou Koulibaly.
According to Sky Sport Italia, the defender is in negotiations to extend the current contract which expires in June 2019.
The Senegal international has been very impressive this season under the guidance of Coach Maurizio Sarri.
During these talks, agent Bruno Satin could also ask for a clause to be put into the contract or at least a verbal agreement made on his price-tag.

There are clubs including Manchester United and Bayern Munich who are interested in a possible swoop for K2.
Koulibaly hit the headlines last month when France Coach Didier Deschamps said he was considering giving the player a call-up, not realising he is already a full Senegal international.
