Kieran Tierney, born on 5th June 1997 and hailing from Scotland, is a solid defender who employs his skills as a left back for Celtic Football Club. Standing at 5ft 10in (1.78m) and tipping the scales at 11st 13lb (76kg), Tierney proudly carries the number 63 jersey. His talents have been recognised at an international level, with appearances for the Scotland National Team.
Presently, Tierney's market value is estimated to be around £7m, as reported by Transfermarkt.
Tierney linked his destiny with Celtic in July 2005 as a trainee, a position from which he surged forth into his debut season 2014 - 2015. During this time, he graced the field on two league matches. 2015 - 2016 saw Tierney take to the pitch 23 times, triumphantly scoring a goal. His performances remained consistent through the 2016 - 2017 season, with another 24 appearances and a scored goal. The 2017 - 2018 season framed Tierney's best achievement in goal scoring, netting three times over 32 matches. Finally, in the 2018 - 2019 season, Tierney made a further 21 league match appearances, before a significant chapter closed in his career.
On August 2019, Tierney steered his career in a new direction, transferring from the Scottish Premiership's Celtic to the Premier League's Arsenal, for a fee around £25m. His time in England started off with 15 league match appearances and a goal (2019 - 2020). He steadily improved his stand with 27 appearances and another goal in the 2020 - 2021 season. Remaining stable, he repeated this in the 2021 - 2022 season. However, the next year (2022 - 2023) he only made 27 appearances without a goal. After a brief dip in 2024 - 2025, he made only 13 appearances but, encouragingly, delivered a goal.
Seeking new horizons, Tierney transferred on loan to LaLiga's Real Sociedad in August 2023. He sailed through 20 league match appearances in the 2023 - 2024 Spanish season, before returning to the Premier League's Arsenal in July 2024.
Back at Celtic in July 2025 after his time at Arsenal, Tierney has made eight appearances for his current season of 2025 - 2026, scoring a goal. Highlighting his active career, he has participated in various tournaments and championships: League Cup 2025 - 2026, World Cup Qualifiers Europe 2024 - 2026, Euro 2024, Euro Qualifiers 2022 - 2024, Champions League Qualifiers 2025 - 2026, Nations League 2024 - 2025 and Europa League 2025 - 2026, representing both Celtic and Scotland.
