ScotlandAvec le Celtic, il a remporté quatre titres de champion d'Écosse, trois Coupes d'Écosse et deux Coupes de la Ligue. Il a également été élu deux fois dans l'équipe-type du championnat écossais et a reçu le prix du jeune joueur de l'année en Écosse.
Kieran Tierney est un arrière gauche écossais formé au Celtic Glasgow, où il a remporté plusieurs titres de champion d'Écosse avant de rejoindre Arsenal en 2019. Il s'est rapidement imposé comme un joueur clé grâce à sa combativité et ses centres précis. Prêté à la Real Sociedad en 2023, il continue de briller en Liga.
Tierney est un latéral moderne alliant endurance, vitesse et qualité de centre, ce qui en fait une menace offensive constante sur son côté gauche. Défensivement, il est solide dans les duels et montre un grand engagement, même s'il peut parfois être exposé face à des ailiers très rapides. Son intelligence de jeu et sa capacité à lire les phases de transition sont des atouts majeurs.
