Same would happen with a Superleague too, unless you make it so that Superleague clubs leave their national leagues altogether. Otherwise PL clubs will keep the financial advantage of having a more popular league worldwide over the rest of the Superleague competition. So say it out loud “we want to end national leagues because the PL is too dominant economically, we want to end the architecture club football has been built on over the past century because someone is doing better than us even though we tried really hard to gain a dominant position with massive tax breaks and loose regulation on debt for decades”.
Either way there was a foul on Dembélé earlier so PSG deserved a penalty in that game.
