Napoli's Kalidou Koulibaly is "flattered" by the persistent speculation linking him with the likes of Manchester United, but he wants to continue improving his game with the Partenopei.

Axar.az reports citing Bleacher that, according to Football Italia the likes of United, Chelsea, Barcelona and Arsenal have all been linked with the central defender, who told Rai Sport he finds ample motivation at his current club.

The Senegal international's future has been a constant talking point throughout the season. According to Football Italia, Napoli value the defender at over €100 million, and owner Aurelio De Laurentiis has already admitted he will likely be sold if clubs keep making "indecent offers," per Corriere del Mezzogiorno (h/t Football Italia).

The 27-year-old committed to a new contract with the Partenopei earlier this season and has been vocal about his love for the city and club, per Sky Italia (h/t Football Italia).

Koulibaly has been with Napoli since 2014 and has developed into one of the world's best centre-backs in Italy. He's regarded as Serie A's best all-rounder, standing out for his aerial prowess, vision and impressive athleticism.

Most of the transfer links have involved United, who have been on the lookout for defensive reinforcements for some time. Things have improved under interim manager Ole Gunnar Solskjaer, but the Red Devils could still use a world-class, experienced operator to pair with rising star Victor Lindelof.
