Koulibaly has been linked with several high-profile clubs having starred in the heart of the Napoli defence, with Manchester United, Liverpool, Manchester City, Paris Saint-Germain and Barcelona all rumoured to be weighing up approaches.
A recent report claimed that Liverpool and Man United had made contact with Napoli regarding a proposed summer move, but Koulibaly has affirmed that he remains committed to the Serie A outfit.
Speaking to La Gazzetta dello Sport, the Senegalese centre-back said: "In football, you never know what happens. I never spoke to Napoli about leaving. If we have to find a solution, we will find it, but I have never talked about the transfer market.
"I also read in the newspapers about my future. But I only want to think about playing, I am 100% [committed to] Napoli and it bothers me to be linked, every day, to this or that European club.
"We will see what the president (Aurelio De Laurentiis) will decide and if he proposes to extend my contract, that would allow me to end my career here.
"At the moment, I still have a three-year contract and I am not thinking of anything else but Napoli."
Koulibaly, who has turned out 19 times in the league this season, would supposedly cost in the region of £72m despite the financial implications of the coronavirus pandemic.
