Napoli defender Kalidou Koulibaly is stalling over signing a new contract – amid reported interest from Chelsea.
The Senegal international has been tipped to leave Italy this summer after enjoying an impressive campaign in Serie A last season.
Both Everton and Chelsea are interested in the centre-back, with the latter reportedly tabling a £38million bid.
After selling Gonzalo Higuain to Juventus for £75.3million, Napoli have no need to sell Koulibaly and they would like him to stay.
But, according to Gazzetta dello Sport, the 25-year-old is currently refusing to sign a new deal with the Italian club.
The defender still has three years to run on his current contract, but Napoli are eager to tie him down with an extended five-year deal.
