Romain Ntamack is one of five new faces in France’s 31-man squad for the upcoming Six Nations.
The 19-year-old, who can play fly-half or centre, was a member of the Les Bleus squad that won the World Rugby Under-20 Championship last year.
Montpellier powerhouse Willemse (6’7, 136kg) was tipped to have played in the November internationals, but was told he had to wait until he received a French passport.
The likes of Teddy Thomas, Yoann Maestri and Mathieu Babillot miss out on selection due to injury.
