Liam Scales, born 8 August 1998, hails from the Republic of Ireland. The 27-year-old puts on a solid defence for Celtic as a central defender, standing at a mighty 6ft 2in (1.88m) and weighing in at 13st 5lb (85kg). You'll spot him on the field in number 5 jersey and, aside from bringing the Celtic spirit to the Scottish Premier League, he also represents his homeland on the international stage as part of the Republic of Ireland national team.
According to Transfermarkt, Scales' current market value is approximately £3.5 million as a testament to his talent and contribution to the team.
Scales started his football career in Ireland, stepping onto the field for UCD in the First Division in January 2017. He left his mark during his debut 2019 season, booting one goal and taking a regular place in 30 games. The defender stepped up to the Premier Division in 2020, joining Shamrock Rovers where he made 16 appearances in his first season, following it up with 23 in the next season, along with two goals to his name.
Celtic welcomed Scales to Scotland in August 2021 for an undisclosed fee. Over the following seasons, Scales proved himself a vital part of Celtic's team. In his first season, he played a part in five league matches, starting the season strong with a goal to his name. The 2023-2024 season saw him up his game, appearing in 34 matches and again contributing on the goal front. The following season, Scales poached two goals in his 26 appearances. As the current 2025-2026 season unfolds, he already had ten appearances under his belt.
A temporary departure saw Scales join Aberdeen on loan in July 2022, where he stepped onto the pitch for 31 league matches and scored one goal. Come June 2023, Scales returned to Celtic to continue defending the Bhoys' goalposts and contributing his striking skills.
Scales' career has seen him compete on various stages beyond the league. He's been a part of Celtic's Champions League 2023 - 2024 team (with six starts), taken part in the League Cup 2025 - 2026 scoring in his single game, and challenged teams in the Scottish Cup 2024 - 2025 with three starts plus a substitute appearance. Internationally, he contributed to the Republic of Ireland's team in the Euro Qualifiers 2022 - 2024 and World Cup Qualifiers Europe 2024 - 2026. Celtic's latest European engagements saw Scales start twice in the Champions League Qualifiers 2025 - 2026 and score once in three Europa League 2025 - 2026 matches. As a key member of Republic of Ireland's Nations League 2024 - 2025 team, he netted yet another memorable goal.
