Atalanta BCAvec Arsenal, il a remporté la FA Cup en 2020 et le Community Shield en 2017. Il a également été élu meilleur joueur de l'année par les supporters de Schalke 04 en 2017.
Sead Kolašinac, défenseur central bosnien, a débuté sa carrière professionnelle à Schalke 04 avant de rejoindre Arsenal en 2017. Il a ensuite évolué à l'Olympique de Marseille et à l'Atalanta Bergame, où il s'est imposé comme un joueur polyvalent et combatif. International bosnien, il a participé à plusieurs compétitions majeures avec sa sélection.
Kolašinac est un défenseur robuste, connu pour sa force physique et son agressivité dans les duels. Il excelle dans les interventions défensives et possède une bonne capacité de relance, mais peut parfois manquer de vitesse face à des attaquants rapides. Son jeu de tête et sa présence dans la surface adverse en font également une arme offensive sur les coups de pied arrêtés.
