Liam Scales, born in Ireland on 8 August 1998 (age 28), is a Republic of Ireland centre-back and current Celtic player, wearing squad number 5. His market value is around £4.5m, according to Transfermarkt.
Scales came through in Ireland and made his name at Shamrock Rovers, where his best league return came in 2021 with two goals in 23 appearances. Celtic signed him from Rovers in August 2021, a move that looked initially like one for the longer road rather than an instant first-team certainty.
That longer road mattered. His loan spell at Aberdeen gave him sustained Premiership football and a harder education than training-ground promise. He returned to Celtic a more credible option, and, when his chance came, he handled the step up with a steadiness that earned him a proper place in the side.
At Celtic, Scales has been part of three Premiership title wins, two League Cups and one Scottish Cup, with a Scottish Cup runners-up finish also on his record. In 2026-27, he has made five league appearances and scored once, along with two League Cup appearances, four in the Scottish Cup, two in Champions League qualifying and one in the Europa League.
He has also remained involved internationally, making three World Cup qualifying appearances for the Republic of Ireland in Europe and one in the Nations League this season. His career has been built in stages: established at Shamrock Rovers, tested on loan, then back at Celtic as a reliable first-team defender rather than a fringe bet.
