Napoli made their captain an "irrefutable" offer - but he's yet to put pen to paper

Napoli are in a state of alert. They are trying to tie their captain Kalidou Koulibaly to a new contract and avoid losing one of their best players to Juventus.

Juve torn between Koulibaly and Milenkovic

The Bianconeri have already made contact with the Senegalese's representatives to try and snatch the 31-year-old defensive rock, who enters his final year of contract at Stadio Diego Armando Maradona.

The Senegal international loves life in Naples, where he enjoys a strong bond with the supporters, but he's allegedly tempted into trying his luck at a club competing on a higher level. To stop Koulibaly from having a dilemma, the Campagna club offered him what their sporting director Cristiano Giuntoli called "an almost irrefutable offer", namely a five-year contract with a net salary of $6 million per year.

"Club president Aurelio De Laurentis offered Koulibaly a huge offer of $60 million gross over five years and a role on the Napoli board at the end of his playing career. Kalidou gave us a lot and he deserves to remain at Napoli in some capacity. But he has to think about it."

Napoli don't want to give their captain up, but will demand a fee of around $35 million should the African star decide his future lies away from Naples.
