Kieran Tierney may now be an established figure at Arsenal, but the firm foundations of his career were laid at Celtic, where he served for several seasons. Born on the 5th of June 1997 in Scotland, Tierney, primarily a defender operating at left back, stands at 5ft 10in (1.78m) and weighs 11st 13lb (76kg). His current market value is pegged around £8.5m, as cited by Transfermarkt. Arsenal's faith in his abilities is clearly reflected by his long-term contract, which doesn't expire until the summer of 2025.
In July 2014, Tierney's journey with Celtic began, and he quickly showed his value to the squad. Even though he only made two first-team appearances in league matches in his debut season, 2014 - 2015, he steadily became a dense pivot in the squad. In the subsequent season, he made 23 appearances and netted his first goal for the club. The following seasons saw Tierney not just solidify his place in the starting eleven but also contribute to the goals, with one goal each in the 2016 - 2017 and 2017 - 2018 seasons, and three crucial goals in the 2018 - 2019 season, despite only making 21 appearances that year.
His sterling performance caught the attention of Arsenal, and in August 2019, they moved to acquire his services from Celtic for an estimated fee of around £25m. His transition to the English Premier League has been pretty seamless — apart from his current 2024 - 2025 season where he hasn't made a first-team appearance. On the offensive front, he has been somewhat consistent, netting one goal each in the 2019 - 2020, 2020 - 2021, and 2021 - 2022 seasons.
Tierney also had a brief taste of LaLiga football when he went on loan to Real Sociedad in August 2023, appearing in 20 league matches. However, his stint concluded in June 2024 when he returned to the Emirates. Despite his impressive performances, Tierney has yet to make a mark in the current 2024 - 2025 season.
