Ayumu Seko

Ayumu Seko developed through Cerezo Osaka before moving to Switzerland with Grasshoppers, where three seasons in the Super League gave him consistent European exposure. His 2025 move to Le Havre in Ligue 1 represents a step into one of Europe's top five leagues, a progression that reflects growing confidence in his abilities as a left-sided defender. Technically assured and comfortable in possession, Seko has built his game through steady progression rather than high-profile transfers. At 26, he is emerging as a credible option for Japan's defensive depth, particularly on the left flank.
