Everton have completed the transfer of Niels Nkounkou on a free transfer from Olympique de Marseille.
The 19-year-old left-back declined the offer of a contract at Marseille and has agreed a three-year deal Everton.
Everton Director of Football, Marcel Brands said: “Niels is a young, talented player with good technical and physical skills. We have been following him for months.
“Hopefully he can learn a lot from Lucas Digne and Leighton Baines, as well as Carlo Ancelotti and David Unsworth, and follow the same pathway into the first team the likes of Dominic Calvert-Lewin and Mason Holgate have taken in recent years.”
