Basically, a power grab by the clubs to take control from UEFA. Now, a properly-run UEFA might garner huge support in this existential battle. And, to be fair, UEFA are not FIFA. But they haven't really done enough for the little guy to garner unquestioned support here.
This is, essentially, the Premier League breakaway all over again. Instead of worrying about 92 clubs, that breakaway allowed the FA to usurp the Football League and consolidate all wealth in 22 clubs, now 20. In the case of this Super League, instead of spreading the wealth across thousands of clubs, it can be crystallised in 80 - with, no doubt, huge differentials in how that is divvied up among the elite. You can bet Florentino Perez does not see, say, Sporting Lisbon, Feyenoord, or Anderlecht gaining a share anywhere comparable to Real Madrid's.
So, this is no solution. What we need is a system that does not consolidate all wealth in the Premier League. That won't change with this. If anything, it simply compensates the super clubs on the continent for the unbalanced TV rights deals that are earned in England and rips away power from regulators. It won't help Steaua Bucharest - who probably won't make the 80, anyway - or even those who do who aren't in the elite 12 or 16.
The solution would be some kind of transparent - and fair - financial fair play rules that reflect the reality that a globalised game with EU freedom of movement means the market alone cannot provide equality of opportunity. In accepting that, we need a system that transfers significant wealth to countries whose cubs cannot compete in the interests of safeguarding the game. Basically, EU structural funds for football. Structural funds from the EU have essentially built up small or poorer countries so they can now compete in the European single market and grow their markets to the benefit of all. Ireland may not be Germany, but it is economically and socially "competitive". Poland has been transformed by EU funds. But Florentino is hardly in favour of ensuring that Romania continues to produce players like Hagi or Bulgaria gives us more Stoichkovs...
