But if we talk about the opportunity to play in a big club, it can give him the opportunity to develop faster because he is motivated to play consistently at all times to become a core player. Usually when there are challenges and pressure it will give great motivation to every player.
If in the end Nico Williams stays endure, maybe he has considered many things so that is the decision he chooses.
Next season he can decide again which club to go to and most importantly he can maintain the consistency of his best playing form so that he will remain one of the players targeted by many clubs.
Nico Williams has been in the spotlight after his impressive performance with Spain at Euro 2024. This has created a hype train and has made many big clubs want to recruit him. But I think his decision to stay with Bilbao is a good one. IMO it would be quite hasty for Nico Williams to accept an offer to another club at this time. By choosing to stay in Bilbao he will have one season to decide whether to stay at San Mamés or can consider another club next season. He is certain to be part of Bilbao's first team this season and if he can maintain his consistent performance, I think it is not impossible that his value will increase next season.
This season, the big clubs in Europe have tried to take him with a lot of interest, but if he does not show such performance in the next season, then the big clubs will not show much interest in taking him.
Nico Williams has been offered by many clubs and if he accepts the offer now he can sign a long-term deal with those clubs and not have to worry about his career. If he decides to stay in Bilbao, he must improve his performance and play the whole season.
It's like a gamble because if he can improve his performance, he may receive offers from top clubs, but if his performance is worse than at present, his demand will decrease. There is still enough time so hopefully he will make the decision that is best for his career.
