Bilbao will lose their valuable asset but they will also benefit from the sale of this player which is clear that Barcelona really wants this player because Barca feels that the combination of Lamine Yamal with this player will be very suitable for next season in deepening their strength as they work together in the European arena so that brings Spain won Euro 2024 thanks to their performance and I think Nico Williams will also be happy because he will join his colleague at the same club.

Somehow it's a win win situation for both teams, one is getting a quality player and the other a ton of money, Bilbao will miss their star but they made some good money of the sales, for Barcelona it's very important to them because they need to do all that they can to get their team in the best shape they can for this season because it's looking like next season is most definitely going to be very different from what they did had last season and they may face more challenges so the best they can do is to strengthen the squad as much a ls they can with the much they have in their purse and are able to spend as at this time.
