Kylian Mbappe's move to Barcelona would be brilliant if finances were right. Barcelona's finances prevent this. Let's not despair: they're still Barcelona, right? Xavi navigated the team through several hurdles last season. Even without major transfers, they can defend their title with the appropriate strategy.
Yep, Barcelona has the problem with their financial. It seems impossible for them to sign Mbappe. They have no money to pay Mbappe's transfer fees and his salary.
