Kieran Tierney, born on 5 June 1997 in Scotland, is a stalwart defender celebrated for his talents as a left back for Celtic. With a physical stature measuring in at 1.78m (5ft 10in) tall and weighing 76kg (11st 13lb), Tierney dons the number 63 jersey with pride. Besides his vital role at Celtic, he's also had the honour of representing the Scotland national team.
As of today, Tierney's market value is pegged around £7.5m, according to Transfermarkt.
With Celtic, Tierney rose through the ranks and joined the Premiership in Scotland as a trainee in July 2005. His first taste of top-tier action came in the 2014 - 2015 season, where he made two first-team appearances for the club. The subsequent years proved fruitful for the young Scotsman as he consistently made over 20 appearances per season, totalling 102 first team appearances and notching five goals between 2015-2019. In the current season of 2025 - 2026, Tierney has already recorded six first team appearances for Celtic.
In August 2019, Tierney made the bold leap from Celtic to join Arsenal in the Premier League for a staggering figure around £25m. His first season with the Gunners was a tentative one, with 15 appearances and a single goal to his name. However, his influence grew over the subsequent seasons; from 2020 to 2023, he made 76 appearances and hit the back of the net thrice. 2024 - 2025 was a touch quieter, with 13 appearances without a goal to his name.
Come 2023, Tierney opted for a change of scenery and transferred on loan to Real Sociedad in Spain's LaLiga. During his loan spell, he made 20 appearances marking his transient but notable presence in Spanish football.
Returning to Arsenal in July 2024 after his stint in Spain, Tierney once again showcased his abilities for the London club, grabbing one goal in 23 appearances until 2025.
In an enchanting twist of fate, Tierney made a triumphant return to Celtic in July 2025, marking an end to his English and Spanish adventures and a homecoming to the Scottish Premiership.
Beyond his commitments to Celtic, Tierney's talents graced various competitions including the 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 the Europa League 2025 - 2026, either starting matches or making notable appearances as a substitute.
