Anthony Ralston, born on 16 November 1998 (age 27), is a Scotland right-back whose career has been shaped overwhelmingly at Celtic. He joined the club from Queen's Park in January 2016 and remains part of the current squad, wearing number 51.
His early years at Celtic included loan football, useful for a young defender needing senior minutes and a bit of hardening. The long-term story, though, has been at Celtic, where he has made 111 league appearances across 12 seasons and scored seven league goals.
Ralston’s most productive league campaign came in 2021-22, when he scored four times in 28 appearances. He has never been a showy player, but his value has usually been plain enough: direct, committed, and reliable when called upon. During his time at Celtic he has won nine Premiership titles, five League Cups and three Scottish Cups.
In 2026-27, he has made four Celtic appearances across all competitions, scoring once, with two outings in the Scottish Cup and two in Champions League qualifying. He has also been involved with Scotland this season, making two World Cup appearances and three in European World Cup qualifying.
Ralston’s market value is around £1.5m, according to Transfermarkt. Now well established as a long-serving Celtic player, his career is best understood as one of persistence within a club where staying power is not handed out cheaply.
