Teenage striker Mathis joins Everton

Updated: 

Everton have signed French youngster Boris Mathis on a two-year contract.

Mathis, 19, was a free agent after leaving Ligue 1 side Metz, where he made his professional debut in April this year.

The striker will initially link up with Everton's under-23 squad but has ambitions to break into Ronald Koeman's plans.

"My dream is to play for the first team here," Mathis told Everton's official website. "Ronald Koeman is a huge figure, not only as a coach now, but his reputation as a player speaks for itself as well. I want to play in the Premier League for Everton."
