Nonetheless, it is entirely up to the player; William may still leave Bilbao due to a personal request. Nico Williams' contract is about to expire, but there is no word on whether he and Bilbao are in talks to extend it. As far as I know, Bilbao has offered him a three-year contract extension, but Williams has not responded.
Barcelona could still sign him during the next summer transfer season. Nico Williams has very good relationships with some of Barcelona's players on the Spanish national team, so he still has a chance to join Barcelona.
Nico Williams is currently focused on helping Spain at Euro 2024 so it is indeed possible that the current issue will not be responded to by him personally, Bilbao has stated that they intend to keep Nico Williams in the squad even though indeed many offers are starting to come from big clubs want to recruit him, I think his contract that is almost ending at Bilbao indicates that there is no certainty about his future with Bilbao at the moment, Especially if indeed he is able to maintain his impressive performance in the Euro later, of course a big offer and also a big salary will come be very difficult for him to refuse, currently the release clause owned by Nico Williams at Bilbao can still be said to be a small value for a big European team.
In my opinion, Nico Williams will of course consider leaving for another club if there is indeed a better offer coming from the big teams that can indeed give him hope of winning of prestigious trophy later, Barcelona desire to recruit Nico Williams is of course very big but their poor finances are of course a barrier to getting Nico Williams at this time, In addition to Barcelona, it is reported that several other teams are also starting to try to recruit him such as Liverpool, Arsenal and Chelsea.
