Napoli president Aurelio De Laurentiis is adamant defender Kalidou Koulibaly will not leave on the cheap.
Liverpool have been linked with the Senegal international ahead of the summer market.
The Serie A side are open to a sale, but not on the cheap, with the Napoli chief confirming his side's stance on Sky Italia.
ADL said, "Kalidou is a wonderful person and of course it'd be sad to lose him. 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."
