This is really quite unbelievable, but in reality should have been expected as the money in the game reached the levels it has, and the inevitable struggled caused by the pandemic.
Ultimately, the biggest clubs have a business model which means they must play Champs League football to survive. Ticket sales, merchandise and broadcast rights bring in colossal amounts of money and has time has gone on, the costs of running have also increased massively (salaries, transfer fee's etc) to the point that you still need an oligarch / billionaire to prop you up. And billionaires are first and foremost, business people. What brings in the money, is all that matters. So as the pandemic as destroyed ticket sales, and then the big clubs losing their colossal fans / cauldron atmosphere's, things have evened up somewhat (as can be seen by the tables). So suddenly all the CL places are up in the air the business boys get together and BOOM. A breakaway league for the rich.
It's shocking, and it shows just how little of the tournament is about the sport now. You've got to earn your right, not buy it, to play European football.
I have no idea how this will play out. I think it will come down to how the players feel. The fans hate it. The pundits hate it. Governments hate it.
But it seems to be set in stone. Interesting times ahead.
