Liam Scales, born on 8th of August, 1998 (age 27) in the Republic of Ireland, patrols the heart of defence for footballing giants, Celtic. Standing at a commanding 6ft 2in (1.88m) and boasting a robust weight of 13st 5lb (85kg), Scales is known for his strength and aerial prowess. He dons the number 5 jersey for Celtic, while also representing his birth country, the Republic of Ireland, on the international stage.
As of the time of writing, his market value hovers around the £4.3m mark, as Transfermarkt suggests.
The promising defender's career took flight at UCD in the First Division in Republic of Ireland, where he joined in January 2017. He clocked up an impressive 30 first team appearances and netted one goal in his debut 2019 season. By January 2020, Scales made a step forward in his career, moving to Shamrock Rovers in the Premiere division of the Republic of Ireland.
During his tenure with the Shamrock Rovers, Scales was a mainstay in the defensive lineup. He made 16 appearances in the 2020 season and 23 appearances in the 2021 season, even managing to score a couple of goals.
Come August 2021, the allure of Scottish football proved irresistible to Scales. He was snapped up by Celtic in the Scottish Premiership, for a sum that remains undisclosed. His first season at Celtic saw him make five first team appearances with a solitary goal. As Scales found his footing in Scottish football, his appearances grew. In the 2023 - 2024 and 2024 - 2025 seasons, Scales racked up a total of 60 appearances and netted a respectable three goals. In the current season (2025 - 2026), he has made 18 appearances to date.
It is worth noting that during the 2022 - 2023 season, Scales spent a loan term at Aberdeen. Despite playing for a different club, he managed to continue impressing with 31 first team appearances and a goal.
His time off from Celtic in 2022 - 2023 seems to have done wonders for the Irishman, as upon his return to Celtic in 2023, Scales has been in excellent form. Accumulating 44 appearances across the 2023 - 2024 and 2024 - 2025 seasons, Scales managed to find the back of the net thrice. In the current 2025 - 2026 season, Scales has featured in 18 games.
The defender further extended his pedigree on the global scale through his participation in international tournaments. Scales played in the Champions League for Celtic in 2023 - 2024 and 2025 - 2026, the latter year included qualifiers as well. On the international stage, he played in World Cup Qualifiers for the Republic of Ireland (2024 - 2026), Euro Qualifiers (2022 - 2024) and the Nations League (2024 - 2025). He also represented Celtic in the Europa League in the 2025 - 2026 season and starred in the League Cup 2025 - 2026. In his international endeavours, Scales managed to find the back of the net once for the Republic of Ireland in the 2024 - 2025 Nations League. On the club scene, he scored once in both the League Cup 2025 - 2026 and the Europa League 2025 - 2026 for Celtic.
