Kieran Tierney is a Scottish professional footballer who plays as a left-back or centre-back for Premier League club Arsenal and the Scotland national team. Tierney came through the Celtic youth system and made his first team debut in April 2015, and his full international debut in March 2016.
Born in Douglas on the Isle of Man, Tierney moved to Wishaw in Scotland aged 10 months.He supported Celtic as a child and signed for the club when he was 7 years old.
He was educated at Motherwell schools St Brendan’s RC Primary and Our Lady’s High then attended St Ninian’s High School, Kirkintilloch, which has a development partnership with Celtic. He has spoken of his hope of emulating the late Tommy Gemmell, a member of the Lisbon Lions team who also grew up in Wishaw and played in the same position.
He progressed through the various youth ranks and earned a reputation as a dependable wide player in the club’s development squad, both in defence and attack. He travelled with the first team squad on a pre-season trip to Finland in August 2014, and made his debut in a friendly against Tottenham Hotspur there.
Although Celtic lost, Tierney described his first appearance for the first team as a “dream come true”. He continued to play in the development squad throughout 2014–15, and in October 2014 during a Development League match against Heart of Midlothian he scored a goal from the edge of his own penalty box.
Tierney made his competitive senior debut for Celtic on 22 April 2015, coming on as an 81st-minute substitute in a Scottish Premiership match against Dundee.
He made one further first team appearance that season, playing over an hour in a league match away at St Johnstone.

Tierney missed the early part of the 2019–20 season, having undergone a double hernia operation in May 2019. He made his first-team debut for Arsenal in a 5–0 win against Nottingham Forest in the EFL Cup on 24 September.
Tierney played for Scotland at Scotland U18 and Scotland U19 levels. He had also considered playing for the Ellan Vannin team that represents the Isle of Man when the ConIFA World Cup competition was being held.
