Born in Scotland on the 5th of June 1997, Kieran Tierney stands as a commendable figure in the realm of football, majestically defending the left side of the field as a left-back. Towering at 5ft 10in (1.78m) and weighing 11st 13lb (76kg), Tierney, now 28 years old, has shown exceptional skills on the turf not only for Celtic, where he impressively dons the number 63 jersey, but also while representing the Scotland national team.
The market estimates Tierney's current value to be around £6.8m, information brought to light by Transfermarkt.
Reminiscing about his early career, Tierney was welcomed into Celtic family as a trainee in July 2005, marking the beginning of his journey. The talented defender began to make waves from the 2014-2015 season, making his two first-team appearances and setting the tone for what was to follow. By the 2015-2016 season, Tierney caught more attention, appearing 23 times and scoring once, which became a hallmark of the time he spent at Celtic, delivering performance after performance in every subsequent season. His most prolific season was perhaps the 2017-2018 stretch, when he made 32 appearances and scored three goals.
However, the lure of English football proved irresistible, and in August 2019, Tierney transferred to Arsenal in the English Premier League for a considerable fee of £25m. Despite adjusting to a new league, Tierney made consistent appearances and contributions to the London side, uncertainty of injury and loan moves aside.
A unique career chapter unfolded in August 2023, when Tierney moved to Spanish club Real Sociedad on loan, subsequently returning to Arsenal in July 2024. Despite his globetrotting career shifts, Tierney maintained his unwavering form and dedication.
Heading back to his roots, Tierney rejoined Celtic in July 2025, welcomed back with open arms by the Hoops fans. Much like his previous tenure at Celtic, Tierney has been an essential element of the team, contributing both through appearances and goals in the recent 2025-2026 season.
His laurels don't stop at club level though. A stalwart for Scotland, Tierney has graced various stages in football including the League Cup 2025 - 2026 for Celtic, the World Cup Qualifiers Europe 2024-2026 for Scotland, and the Europa League 2025-2026 for Celtic, showing unfaltering commitment and perseverance even in the face of the pressure of the beautiful game.
