Kieran Tierney, born on 5 June 1997 and currently 28 years old, is a stalwart of Scottish football. The lad from the home turf has made quite a name for himself primarily playing as a left back for Celtic. He stands at a height of 1.78m (5ft 10in) and weighs in at 76kg (11st 13lb). He dons the number 63 jersey and has also graced the field as part of the Scotland national team.

Tierney's journey with Celtic began in July 2005 when he joined the Scottish Premiership club as a trainee. After some initial seasons of making his way through the ranks, his breakout came in the 2014 - 2015 season, where he made his first two appearances in league matches. Over the ensuing seasons at Celtic, his presence grew stronger, culminating in the 2017 - 2018 season where he made 32 first team appearances and scored three goals.
In August 2019, Tierney embarked on a new adventure as he signed for Arsenal in the English Premier League for a sum hovering around the £25m mark. He took his solid work attitude and robust defensive skills to the English side, making consistent appearances and continuing to find the net in each of his seasons with the Gunners.
A temporary sojourn came in August 2023 when he transferred on loan to Real Sociedad in Spain's LaLiga, where he continued to make a significant impact with 20 first team appearances.
Completing his loan spell in July 2024, Tierney returned to Arsenal before eventually heading back to his roots at Celtic in July 2025. His homecoming season saw him continue his sterling defensive performances with ten first team appearances to his name, and one goal scored.
Throughout his career, Tierney has also shown commendable performances in both national and international tournaments, most notably for Scotland in Euro 2024, World Cup Qualifiers Europe 2024 - 2026, and Nations League 2024 - 2025, as well as for Celtic in various League Cup and Europa League seasons.
