Everton will reportedly consider selling Yerry Mina this summer if the defender's £21m valuation is matched.
The Colombia international is rumoured to have recently informed the Toffees that he wants to join a Serie A club.
According to Tuttomercatoweb, Everton are not against the idea of selling Mina and bringing in a high-profile replacement.
The report suggests that Napoli's Kalidou Koulibaly, who Carlo Ancelotti worked with at the Diego Armando Maradona Stadium, is one of those being eyed up.
Koulibaly would cost just short of £43m, though, meaning that the Merseyside outfit would have to raise funds through player sales.
Everton are expected to face competition for the 29-year-old from the likes of Real Madrid, Liverpool and Manchester United.
