Adam Montgomery, born on 18 July 2002 (age 24), is a Scottish left-back who joined Celtic from Aberdeen in June 2022. Celtic gave him the early platform in his senior career, and his time at the club has included two Premiership title wins, in 2021/22 and 2024/25, along with a League Cup.
His development has since taken him away from Celtic for regular football, rather than leaving him parked on the edge of things. The most productive league spell of his career so far came at Queenβs Park in 2024/25, when he scored once in 12 appearances.
Montgomery remains a Celtic player and is currently on loan at Livingston, wearing squad number 54. In 2026/27 he has made two Championship appearances, with his form described as steady, consistent and unspectacular β which, for a developing full-back, is not the worst place to be.
His career to date is that of a Celtic-developed defender still trying to turn loan football into firmer senior footing. The next step is plain enough: play regularly and make the left-back role feel like his own.
