West Bromwich Albion have announced that teenager Jonathan Leko has agreed his first professional contract at The Hawthorns.
The 17-year-old's deal will keep him tied down to the Premier League club until the summer of 2019.
Leko made his Premier League debut for the Baggies in April at the age of 16 when he came on as a substitute in the 78th minute against Sunderland at the Stadium of Light in April.
In the same month, Leko, who joined the club when he was 11 years old, made his full top-flight debut in a defeat to West Ham United at The Hawthorns.
The forward became the first player born in 1999 to feature in the Premier League.
