The teenager, who turned 16 earlier this year, attained the rights to play for the first-team.
Dembele caught everyone’s attention when he made his U-20 debut at the age of 13.
He has represented Scotland’s U-16 side eight times, while also earning three caps for England’s U-15 side.
Born in London, Dembele can represent England, Scotland and Ivory Coast at the international levels.
Now, he sees his future with England, despite being brought up in Glasgow.
The Hoops prospect took to Instagram to share this message.
Dembele is having a great season with the Hoops’ reserves and U-20 squad. He continues to amaze the fans with his brilliant skills week in and week out.
The Hoops will be playing in the Youth Cup final against their arch-rivals Rangers this weekend at Hampden Park.
