Kieran Tierney

1.1. Birth and Early Education

Kieran Tierney was born on 5 June 1997, in Douglas, on the Isle of Man. At just 10 months old, his family moved to Wishaw in Scotland, where he was raised. He grew up in Motherwell and attended St Brendan's RC Primary and Our Lady's High. During his time at Our Lady's High, he was one year group behind fellow footballers, twins Nicky Cadden and Chris Cadden. He later attended St Ninian's High School, Kirkintilloch, which maintained a development partnership with Celtic. From a young age, Tierney was a devoted supporter of Celtic, a club he would later join. He has often spoken of his aspiration to emulate the late Tommy Gemmell, a legendary member of the Lisbon Lions team, who also hailed from Wishaw, specifically Craigneuk, and played in the same left-back position.

1.2. Celtic Youth System

Tierney joined Celtic's academy at the age of seven, driven by his family's fervent support for the club. He consistently progressed through the various youth ranks, building a reputation as a highly dependable and versatile wide player within the club's development squad, excelling in both defensive and attacking roles. His dedication and talent were recognized early; in August 2014, he traveled with the first-team squad for a pre-season tour in Finland. During this tour, he made his debut in a friendly match against Tottenham Hotspur. Despite Celtic's defeat in that game, Tierney described his first appearance for the senior team as a "dream come true." He continued to play for the development squad throughout the 2014-15 season, notably scoring a remarkable goal from the edge of his own penalty box during a Development League match against Heart of Midlothian in October 2014.

2.1. Celtic

Tierney's tenure at Celtic was marked by rapid ascent from youth prospect to a key first-team player, contributing to multiple domestic triumphs before his move to England.

2.2. Arsenal

Tierney's move to Arsenal marked a new chapter in his career, characterized by both impressive performances and persistent injury battles.

3.1. Youth National Teams and Senior Debut

Kieran Tierney represented Scotland at both U-18 and U-19 levels, showcasing his potential from a young age. He also considered the possibility of playing for the Ellan Vannin football team, which represents the Isle of Man, during the ConIFA World Cup competition.

Tierney received his first call-up to the senior Scotland squad on 10 March 2016 for a friendly match against Denmark. He played the entire first half of the match, which Scotland won 1-0 at Hampden Park, before being substituted at halftime by his then-Celtic teammate, Charlie Mulgrew.

3.2. Versatility and Leadership in National Team

Kieran Tierney's ability to adapt to different roles has been a significant asset to the Scotland national team. Due to his greater versatility compared to fellow left-back Andrew Robertson, Tierney has been deployed in various positions. He played as a right-back in matches against Slovenia, Lithuania, and Slovakia. In addition, he featured on the left side of a three-man defense during the World Cup qualifiers in 2017, particularly in the home fixture against England.

In November 2017, Tierney was honored with the captaincy for Scotland in a friendly match against the Netherlands, where he played as a centre-back in a 1-0 defeat. This demonstrated the trust placed in his leadership abilities. However, in October 2018, he scored an unfortunate own goal in a 2-1 loss to Israel during a UEFA Nations League fixture. Following that game, Andrew Robertson publicly stated that both he and Tierney were being played out of their natural positions in the 3-5-2 system adopted by then-manager Alex McLeish, a system designed to accommodate both talented players in the starting lineup.

3.3. Major Tournaments and Key Contributions

In November 2019, Tierney withdrew from the Scotland squad for their UEFA Euro 2020 qualifiers against Cyprus and Kazakhstan due to a hip injury. In October 2020, he was required to pull out of the squad for a Euro 2020 play-off semi-final against Israel after being in close contact with Stuart Armstrong, who had tested positive for COVID-19. It was later confirmed by Armstrong, Tierney, and Ryan Christie that they had been playing video games together in the same room.

Tierney showcased his playmaking ability by providing three assists in a dominant 4-0 victory against the Faroe Islands on 31 March 2021, despite playing from a central defensive position. He then participated in two of Scotland's matches at the delayed UEFA Euro 2020 finals in June 2021, missing the opening group stage match against the Czech Republic due to an injury setback.

Tierney scored his first goal for Scotland on 24 March 2022, in a friendly match against Poland at Hampden Park, which ended in a 1-1 draw. Soon after, he suffered another training ground injury that sidelined him for the remainder of the 2021-22 season. This unfortunate timing meant he was unavailable for a crucial World Cup playoff against Ukraine in June, which Scotland subsequently lost 3-1.

Despite his injury history, Tierney played a vital role in Scotland's successful UEFA Euro 2024 qualifying campaign, appearing five times. The team remarkably won all five matches in which he played, conceding only one goal during those fixtures. On 7 June 2024, Tierney was officially named in Scotland's squad for the UEFA Euro 2024 finals in Germany. A week later, he started the tournament's opening match, playing 76 minutes before being substituted for Scott McKenna, as Scotland suffered a 5-1 defeat to the host nation, Germany. Tierney's tournament participation was cut short when he was substituted with an injury in the 61st minute of Scotland's second group match against Switzerland on 19 June. This injury rendered him unavailable for the final group stage match against Hungary, which Scotland lost 1-0, ultimately finishing at the bottom of Group A with a single point from three matches.

4.1. Personal Background and Interests

Beyond the pitch, Kieran Tierney maintains strong ties to his roots. In June 2021, he became an ambassador for the Scottish Society for Prevention of Cruelty to Animals (SSPCA), demonstrating his commitment to animal welfare.

During his youth career at Celtic, Tierney had a cherished possession: a pair of football boots gifted to him by former Japan international and Celtic legend Shunsuke Nakamura. Tierney has openly described Nakamura as his "hero," a sentiment that highlights the impact of senior players on aspiring young talents. He also vividly recalls attending his first Old Firm Derby on 16 April 2008, a match made memorable by Nakamura's spectacular goal from approximately 98 ft ^{(30 m)} distance. This particular goal and its significance in Glasgow's footballing folklore have been widely discussed.

More recently, during his loan spell at Real Sociedad, Tierney found himself living on the same street in San Sebastián as Japanese international teammate Takefusa Kubo, fostering a unique bond between the two players off the field.
