Chelsea reportedly told Napoli man is not for sale, Everton also linked

Sky Italia are reporting that Napoli have told Chelsea that Kalidou Koulibaly is not for sale.

It comes after Italian press reports on Wednesday that the Blues had made a €45m (around £37.7m) bid for the centre-back.

Those reports stemmed from journalist Gianluca Di Marzio - whose father Gianni was previously Napoli boss and a transfer adviser to QPR - claiming that Chelsea had submitted the offer. 

Everton are also said to be interested in Koulibaly, with the Merseyside club’s new owners reportedly determined to sign him.
