Napoli coach Luciano Spalletti has confirmed star defender Kalidou Koulibaly is up for sale.
The Senegal international has been linked with Everton and Manchester United this summer, with the latter failing with a €30m offer last week.
Spalletti revealed: "I want to chain myself to all players, and as I have already said, I will be happy if the squad remains intact.
"I mentioned Koulibaly just because he is available on the market, but I would like him to stay.
"I have always worked with someone so well, not only as a player, but also as a person."
