I think I have come up with the perfect punishment for Juventus, Barcelona and Real Madrid.
Instead of banning them, which will never happen, they should wipe out their UEFA coefficient.
This way they're still in the competition, which satisfies sponsors and doesn't rock the boat too much, but they lose the protections they usually have and we will get some real groups of death. Big sides will go out which should spice up the competition perfectly.
It takes 5 years for them to get back to where they were, but the punishment declines. They'd be in pot 4 for 2 years, pot 3 for 2 years and then they'd be back in pot 2.
