Barcelona got a very good win, but they need to sign very good players next year. It was a great season for Real Madrid and they had a serious economic income in all lanes. For Barcelona, it has not been a very good season economically. Therefore, they should make more logical and on-site transfers. I am sure that next year will be a very competitive year between Barcelona and Real.
Yes, their success in recruiting players will greatly affect their game next season. Because if only one thing does not meet expectations, I think it will also be felt, especially in their current financial condition, which must be smart to accommodate their expenses.
Xavi Hernandez in his first season managed to build the Blaugrana out of adversity. Hopefully that success will increase even more.
