Le Havre ACBien qu'il n'ait pas encore remporté de trophée majeur en club, Seko a été sélectionné en équipe nationale japonaise, participant à des matchs de qualification pour la Coupe du Monde. Il a également été un pilier de la défense du Cerezo Osaka en J1 League.
Ayumu Seko est un défenseur central japonais qui évolue actuellement au Havre AC. Il a débuté sa carrière professionnelle au Cerezo Osaka avant de rejoindre le club français en 2023. Seko s'est rapidement imposé comme un élément clé de la défense havraise grâce à sa régularité et son engagement.
Seko est un défenseur robuste et discipliné, excellent dans les duels aériens et la lecture du jeu. Il privilégie la sécurité et la simplicité dans ses relances, mais peut parfois manquer de vitesse face aux attaquants rapides. Son positionnement intelligent compense souvent ce léger défaut.
