Scotland Under-21 international Billy Gilmour has signed his first professional contract with Chelsea.
The former Rangers youth prospect, who turned 17 last month, moved to London for a "significant fee" last year after rejecting an offer to stay at Ibrox.
The midfielder is a member of Chelsea's Under-18 squad but made his debut for Scotland Under-21s this summer.
He won the Best Young Player trophy at the Toulon Tournament after helping the Scots reach the semi-finals.
His international team-mate, Fraser Hornby, has also just signed his first professional contract at Everton.
