Nico Williams and Barcelona have already agreed on personal terms, so I believe Nico Williams signing for Barcelona this season is possible unless Barcelona fails to pay Nico Williams transfer fee at once before a deal that will see Nico Williams move to Barcelona won't happen this season. Yes, Barcelona is finding it difficult to pay Nico Williams's transfer fee at once because of their financial crisis, but they should source for funds and pay for Nico Williams's transfer fee before another club hijacks the deal from them.
I think Barcelona is doing the right thing by strengthening their squad, even though they already look very good. The team still needs to improve. They wanted to sign Nico Williams last summer, but he decided to stay at Athletic Bilbao for one more season. Honestly, maybe there wasn’t much point in that because he couldn’t win anything with Bilbao. I believe he’ll have many more opportunities with Barcelona. I think they will try to win La Liga again, and he’ll play in the Champions League, so personally for him, it’s a big step forward.
