Williams has grown into a vital part of both Athletic Club and the Spanish national team. The 22-year-old scored 11 goals and provided seven assists in 2024-25 in the wake of playing a key role in Spain's Euro 2024 success. His performances have turned heads across Europe and with a relatively modest release clause, he is within reach for top clubs.
However, according to Estadio Deportivo, Los Leones are not giving up easily. Talks to renew his contract have officially begun, with the club offering a significant salary hike reported to be around €10 million (£8m/$11m) per season.
