I frequently ever hear anything about Seria. In contrast to Barcelona, a Spanish league club. I believe the blaugrana are to blame for their own difficulties, as they violated FFP guidelines by signing players for exceeding the expected budget generated and offered by the club. The same scenario happened to Chelsea several years ago, and they were banned from signing players for an unknown length of time. Clubs cannot go bankrupt because they have high businesspeople who have invested significantly in a club, a single individual can own a club and shares, and he can build the club despite the imposed responsibilities and debts.
As far as I know, Barcelona isn't a club that is carried by these typical investors as we know them from Chelsea, Manchester City or PSG. They are selling club assets to refinance and they also take on more debt, more loans every year. I never completely understood how that can work out forever and now they are not even the club anymore that they used to be when they had Messi, Neymar and Suarez. I could understand it back then because it was a tempting investment even to give them an expensive loan as they were able to pay back. But what about these days when there is only one title, early elimination from the Champions League, no Copa del Rey title and no really big names in the team? Please don't say Lewandowski now as he is old and will be gone soon anyway.
