As much as I don't like 'Oil Clubs', reality is that we are more likely to continue seeing more and more "state backed" clubs, bigger transfer fees and more overpriced players.
I hate the model of American sport leagues (no lower divisions, confederations within the same country, all franchises), but what I do like about them is their financial/sport rules... Leagues like NFL, NBA or MLB impose restrictions to clubs, have a salary cap, a sportive transfer system and boost competition. It's uncommon in American sports to see a team winning their League 9 times in a row like Juventus, Bayern or PSG.
I would bet for UEFA, European Football or a "Superleague" that mimics these statutes... Unfortunately, UEFA is far from considering this type of model and will continue to support Oil money.
I remember some years ago talking about the possibility of certain teams leaving FIFA regulations and to create their own new Football association... It didn't happen but Superleague did happen and it was backlashed by UEFA/FIFA immediately. This means that any counter to Oil Clubs will face strong legal actions by UEFA.
Other leagues that were aiming for strong international level and recognition ultimately failed... Chinese league is broken, Indian League didn't last 3 years, Japanese league only has Iniesta, Russian league teams also got broke.
The Spanish League under Javier Tebas is a joke financially speaking. Barcelona - if it weren't for the global value of their brand - would have already filled for bankruptcy. Real Madrid, although on much better numbers than Barsa, are uncapable to match the spending of the Premier League top teams, and Atletico depend too much into the squad Simeone has built so far. Aside from Sevilla, Valencia or Villareal, the rest of the teams are unable to spend more than 5-10 million transfer fees. Their situation got worst with Covid.
