It is worth noting that Williams has been on Barcelona's radar for some time. In fact, he came close to joining the club last summer, but ultimately decided to stay with Athletic Club.

Williams has a release clause in his contract worth €58 million. However, this clause has a condition: the full amount must be paid at once, rather than in installments.

Several top clubs, including Arsenal, Chelsea, Bayern Munich, and Real Madrid, have expressed interest in signing Williams. Interestingly, he seems to prefer staying in Spain.
