Napoli president Aurelio De Laurentiis has opened the door to selling Kalidou Koulibaly by setting an £81m asking price.

The Senegal international has been the subject of intense speculation in recent months with several Premier League clubs thought to be interested.

Manchester United, Liverpool and Manchester City have all been linked with the centre-back, who is regarded as one of the best in his position in Europe.

The 29-year-old, who moved to the Stadio San Paolo from Genk in 2014, still has three years left to run on his current contract and will not come cheap.

But De Laurentiis has for the first time seemingly opened the door to an exit by putting a price-tag on his head.

“Kalidou is a wonderful person and of course it’d be sad to lose him,” the Napoli chief told Sky Italia.

“Everything has a time and a place, even when it comes to going our separate ways.

“Having said that, we don’t have €90m (£81m) on the table and in any case, it takes two to separate.”

Koulibaly helped Napoli seal their first silverware for several years a few weeks ago as they beat Juventus in the Copa Italia final.

But while the defender has always insisting he is happy to remain in Naples, he did not rule out a move when quizzed recently on the matter.

“In football, you never know what happens. I never spoke to Napoli about leaving,” he told Gazzetta dello Sport.

“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 per cent [committed to] Napoli and it bothers me to be linked, every day, to this or that European club.

“We will see what the president 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.”
