Adam Montgomery signed his first professional contract with Celtic FC in July 2019.
During his spell with the U15 squad, Adam scored the winner as the young Hoops triumphed in the prestigious Foyle Cup with a 1-0 victory over Derry Colts in the final.
The talented yongster progressed to the reserves from the club’s Under-17s.
Montgomery started out as forward at the club before being moved into defence by coach Darren O'Dea, and that paid off in February 2021 when the youngster extended his contract to 2025.
And that paid off even further a few months later when, as an 18-year-old, Montgomery made his first-team debut on May 12, 2021 when he started in a 4-0 win over St Johnstone, and three days later he also came off the bench at Easter Road against Hibernian.
