Kieran Tierney, born on 5 June 1997, hails from Scotland and currently wears the number 63 jersey for Celtic as a robust defender. Standing at 5ft 10 inches (1.78m) in height and weighing 11st 13lb (76kg), Tierney plays primarily as a left back, and his prowess on the field is recognised not only by his club but also by the Scotland national team, for whom he has also turned out.
His performance and skills, presumably honed from his time as a trainee at Celtic starting from July 2005, are reflected in his current market value of around €8.00m (£6.8m) according to Transfermarkt.
Looking back at his time with Celtic before his departure in 2019, Tierney made a total of 102 first team appearances in league matches across five seasons. His first taste of first team football came in the 2014 - 2015 season with two appearances. After his debut season, Tierney grew into a prominent player for Celtic, scoring one goal on 23 first team appearances in the 2015 - 2016 season, repeating the feat in the 2016 - 2017 season with 24 appearances. His goal tally increased to three in the following 2017 - 2018 season where he made 32 appearances, and made 21 appearances in the 2018 - 2019 season.
In August 2019, Tierney departed Celtic and made his journey south to join Arsenal in the Premier League for a fee of about £25m. He played for Arsenal from 2019 until 2023, amassing a total of 104 appearances and scoring four goals across five seasons. During the 2023 - 2024 season, Tierney was loaned to Real Sociedad in Spain's LaLiga, making 20 first team appearances.
Upon the completion of his loan, Tierney returned to Arsenal in July 2024. His second stint at Arsenal was relatively quiet, with only 13 appearances and a single goal in the 2024 - 2025 season. Then, with the winds of change blowing once more, Tierney returned to Celtic in July 2025.
Back in the familiar green and white, Tierney's current 2025 - 2026 season with Celtic sees him back in stride with 19 first team appearances and three goals. His performance led to his participation in various competitions such as the League Cup 2025 - 2026 for Celtic (with three starts and one substitute appearance), the World Cup Qualifiers Europe 2024 - 2026 for Scotland (scoring one goal in three substitute appearances), the Champions League Qualifiers 2025 - 2026 for Celtic (with two starts), Nations League 2024 - 2025 for Scotland (with two substitute appearances), and the Europa League 2025 - 2026 for Celtic (with six starts).
Indeed, the story of Kieran Tierney stands as a testament to steady growth, remarkable skill and unyielding dedication to the beautiful game.
