Williams' commitment to Athletic is seen as a fulfillment of his long-term plan, aligning with his career aspirations and loyalty to his boyhood club. He is a product of Athletic's renowned youth academy and made his first-team debut in 2020. Since then, he has become a key player for the club, amassing 122 appearances.
Williams had always envisioned playing European football with the Basque outfit and the team's fifth-place finish in La Liga last season secured their spot in the Europa League, where Williams aims to shine. Additionally, the 2024-25 Europa League final will be held at San Mames, adding another layer of motivation for him to remain with Athletic and potentially lead them to glory on home turf.
