Kieran Tierney, born on the 5th of June 1997 in Scotland, is a robust defender who is recognised for his exceptional play as a left-back for Celtic. Standing sturdy at 5ft 10in (1.78m) tall and with a weight of 11st 13lb (76kg), he proudly wears the number 63 jersey. Besides his club commitments, Tierney has also had the privilege of representing the Scottish national football team.

As per the information available on Transfermarkt, Tierney's current market value is roughly £7.5m.

The talented footballer started his professional journey with Celtic in the Scottish Premiership, joining as a trainee in July 2005. His initial season, 2014-2015, saw him make a modest two first-team appearances in league matches. However, his time at Celtic saw a steady progression. With each season that passed, Tierney's involvement grew, reaching a peak in the 2017 - 2018 season when he made 32 first-team appearances and netted three goals. Before leaving Celtic in August 2019, he wrapped up his last season, 2018 - 2019, with 21 first team appearances.

In August 2019, Tierney found himself experiencing the English Premier League as he made a significant move from Celtic to Arsenal for a staggering fee of around £25m. His tenure at Arsenal saw decent game time, with him making between fifteen to twenty-seven first team appearances in league matches per season, and scoring a few goals along the way.

Taking a brief sojourn from England, Tierney was loaned out to Real Sociedad in Spain's LaLiga in August 2023. His stint here saw him make twenty first team appearances in league matches for the 2023 - 2024 season. Following the completion of his loan, Tierney returned to Arsenal in July 2024, continuing to feature regularly for the Gunners.

However, in July 2025, the Scottish left-back decided to return to his old stomping ground, transferring back to Celtic in the Scottish Premiership. Back in familiar territory, Tierney once again donned the Celtic jersey and made a respectable four first team appearances in his current season, 2025 - 2026.

Aside from his league commitments, Tierney also engaged on the international stage; participating in numerous cups and qualifiers, including the League Cup 2025 - 2026 for Celtic, Euro 2024 and Euro Qualifiers 2022 - 2024 for Scotland, Champions League Qualifiers 2025 - 2026 for Celtic, and Nations League 2024 - 2025 for Scotland.
