Kieran Tierney

Kieran Tierney is a Scottish left-back who came through Celtic's academy and went on to play for Arsenal before returning to Celtic in 2025. He has been capped over 50 times for Scotland and appeared at UEFA Euro 2020 and Euro 2024.

Tierney made his Celtic debut in April 2015 and quickly established himself as one of the best young full-backs in Scottish football, winning multiple Premiership and cup titles. Arsenal signed him in August 2019 for around £25 million, and he went on to make 144 competitive appearances for the club, including a season-long loan at Real Sociedad in 2023–24.

He returned to Celtic in June 2025 on a five-year contract and helped the club win the Premiership and Scottish Cup in his first season back.
