Newcastle United have signed 17-year-old defender Kevin Mbabu from Swiss side Servette.
Mbabu, who is predominantly a centre-back, has agreed a three-and-a-half-year deal after a successful trial and will go into the club's development squad.
The Switzerland Under-19 international told the club's official website: "I am delighted to join Newcastle United.
"Today is a big day for me. I've always wanted to sign for a club in the Premier League and Newcastle is one of the biggest there is.
"I want to finish my development here with the reserves before one day training with the first team and hopefully breaking into the first team.''
