Both Manchester United and Manchester City have been linked with a potential move - perhaps most notably Pep Guardiola's side, as they seek a partner for Aymeric Laporte. Chelsea too, with Frank Lampard wanting to stiffen up his defence, says the Mirror.
“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."
