Size is no protection... plenty of large corporations get into financial difficulty when they overstretch themselves and see income plummet just when they need to invest. Barca may have huge income but you have no cash reserves... just massive liabilities.
Just massive liabilities, nothing else eh? I think that's a pretty naive conclusion
None of those big corporations to fail were in a similar situation as Barca. The only thing that can continue to hurt the club is COVID preventing fans back to the stadium along with the football tourism that comes to the city. Steady income, a new stadium to increase revenue further, stadium naming rights, La Masia to produce local talent and better financial management to avoid the wage disaster Barto et al were guilty of is what is needed more than anything
It's currently a mess but there is a course correction coming which makes the gloom & doom prognostications infantile
