Tierney's football journey began in the Celtic youth setup as early as July 2005, and he would go on to make his first team debut in the 2014-2015 season. His time at Celtic was marked by opportunity and growth as over the ensuing seasons he made regular appearances for the team, gradually increasing his contributions to the game and the scoreboard. His defining season at Celtic was the 2017-2018 season where he made 32 first team appearances and bagged three goals in league matches. In the 2018-2019 season, he made a further 21 appearances for Celtic, testament to how valued he was to the team's line-up. The 2024-2025 season presented him with no appearances, leaving the Hoops without his familiar defensive strength on the pitch.
In a decision that would change the course of his career, August 2019 saw Tierney make the move from Celtic in the Scottish Premiership to join the ranks of Arsenal in the Premier League in England for a significant fee of around £25m.
His time at Arsenal saw his number of appearances fluctuating but remaining consistent overall in each season. His inaugural season of 2019-2020 presented him with 15 first team appearances and a single goal. In the 2020-2021 and 2021-2022 seasons, Tierney played in 27 and 22 first team matches respectively, scoring one goal in each season. The 2022-2023 season saw him feature in 27 matches for the Gunners without adding to his goal tally.
July 2024 marked a passing chapter in his career as Tierney spent a season on loan to Real Sociedad in the La Liga league in Spain, where he featured in 20 first team appearances. His return to Arsenal in the 2024-2025 season saw more of the pitch, making 13 first-team appearances along with an addition to his goal tally.
Throughout his career, Tierney has also had the honour of representing Scotland in international competitions, making appearances in both the Euro 2024 and the Nations League 2024 – 2025, as well as participating in the Euro Qualifiers 2022 - 2024.
