Liam Scales was born in the Republic of Ireland on 8th August 1998, making him currently 27 years of age. The defensive stalwart has established himself as a vital cog in Celtic's backline, predominantly plying his trade as a central defender. Standing at a towering 1.88m (6ft 2in) and weighing 85kg (13st 5lb), Scales proves to be an intimidating presence for opposition attackers. His national allegiance is pledged to the Republic of Ireland, his country of birth.
Scales is also notable for his stunning market value which is reported to be approximately €5.00m (£4.26m), according to Transfermarkt.
Previously, in 2017, Scales signed for UCD in the First Division in the Republic of Ireland for an unknown fee. In his debut season in 2019, he made 30 appearances and managed to find the back of the net once. A year later, Scales moved on from UCD to Shamrock Rovers in Ireland's Premier Division. Over the course of two seasons, 2020 and 2021, he made a combined total of 39 league appearances and tucked away two goals.
In a significant move in August 2021, Scales departed Shamrock Rovers to join Scottish giants Celtic, with the transfer fee remaining undisclosed. In his initial season, 2021-2022, at Celtic, he played five matches and scored once. Scales was then loaned to Aberdeen for the 2022-2023 season where he made a notable contribution of 31 appearances and a goal. However, the following seasons saw Scales back in a Celtic shirt, where he has thus far made 81 appearances and has found the back of the net four times till the 2025-2026 season.
Beyond domestic football, Scales has also participated in a variety of tournaments.
