Adam Montgomery, born in Scotland on 18 July 2002 (age 24), is a left-back on Celtic’s books and currently on loan at Livingston. He joined Celtic from Aberdeen in June 2022, giving him an early place in the system before much of his senior football developed elsewhere.
His Celtic spell has carried the usual odd shape of a young player trying to turn promise into regular minutes. He has been part of a period that brought two Premiership titles, in 2021-22 and 2024-25, and a League Cup, along with a runners-up finish in the league.
Loans have formed a sizeable part of the story. His most productive league campaign came at Queen’s Park in 2024-25, when he scored once in 12 appearances. That was modest enough, but useful experience for a full-back still building a senior career rather than merely collecting squad numbers.
In 2026-27, Montgomery has made two Championship appearances for Livingston while still a Celtic player. His career so far is that of a developing Scottish left-back with a Celtic connection at the front end, and a body of senior football being built away from Parkhead.
