Easy solution. Let real Madrid, Barcelona and Juventus go off and form their "super" league (European Super League) as these are the biggest clubs in the world (as proven by the huge piles of cash they each have in the bank). Their footballing superiority will be shown by not having relegation.
Then these three simply play each other each week from August until May, every year, forever. There will be full houses in the stadiums and a world-wide TV audience of 227 billion (using the same formula that Qatar used for counting attendances in the World Cup).
The winners of the league will be crowned as super champions, the runners-up as premier champions and the third placed club will be championship champions.
If that doesn't satisfy demand to see these giants play, there will be the ESL Challenge Cup, the ESL League Cup and the ESL Champions League (with guaranteed entry to the round of 3). The winners, runners up and third place of each of each competition will qualify for the European Super League Super Cup.
Each year, the winners of the European Super League Super Cup will play the runners-up of the European Super League Super Cup in the Super European Super League Super Cup.
Annually, there will be a match between the winners of the European Super League Super Cup and the Super European Super League Super Cup for the prestigious Super European Super League Super Trophy.
Cant wait...
