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.
A player like Nico Williams is actually very suitable if he wants to be in the Premier League by being in one of the teams you mentioned, because in La Liga he must at least be at Real Madrid if he wants to get trophies in his career. Because if he is at Barcelona, of course there will be very little chance of getting a trophy next season because Barcelona's rivals are still quite strong, like Real Madrid. However, considering going to the Premier League will always be more suitable for him if he is offered by a big team like the one you mentioned.
In my opinion, Nico Williams' performance in La Liga last season is not a very convincing performance in the sense that if he were to join a big premier league team he would improve that team's performance, given the market value that Nico Williams has in this season. at the moment which is €60.00 million, I think it would be much better for the big premier league teams to look for other better options in terms of signing a striker who has scored a lot of goals and managed to play most of the games of the season and has a value low market. the problem with most premier league teams (manchester city don't make these mistakes constantly) is that they have constantly made the mistake of spending a lot of money on signings that don't help the team much and when you look at the performance of that player at the time of hiring, realize that it doesn't make sense to hire
and about Nico Williams I also read this news:
ico Williams’ contract includes release clause worth almost €58M already valid 👀⚡️
Three Premier League clubs and Barcelona depending on Financial Fair Play are all interested in Nico Williams.
“The interest is normal but Nico is very happy in Bilbao, we’re not worried”, Athletic Club president Uriarte said.

It also seems to me that Bilbao won't sell Nico Williams, so I hope to see him at Bilbao next season
