The story of Barcelona and Nico Williams is on again...
They aren't the only team interested in him though. Bayern Munich is also after him. But just as it says in the source, Nico prioritizies Barcelona. He probably wants to play side by side with Yamal as well.

I also hope to see him there. They are already a deadly duo at the Spanish national team.
I don't know if Barcelona can allocate a budget for such a transfer when they have a serious financial responsibility. If they have the financial power, why not, but from what I see, there are only a few rumors, we will see if there will be more.
They are going through a difficult period and they need to think in detail about every transfer they will make. Therefore, it will be very difficult to make calculations, allocate a budget, etc

If Barcelona cannot sign Nicole Williams, it means that Bayern Munich would use the opportunity to sign him since they also have interest in him. Of course, Barcelona financial problem can deprive them from signing Nicole Williams because it will definitely affect them. Players salaries were cut down and younger players from the academy was brought in to fill up the vacuum since the club is broke and doesn't have funds to sign senior players. I wonder how they will make this possible.
