Every single supporter group has condemned this, everyone within football has too - it's an exercise in greed from the owners.
German clubs might resist thanks to the 51% rule (with the exception perhaps of Leipzig), but I expect PSG will join once the backlash settles down.
I really hope the Premier League, La Liga, Serie A stand firm and do kick the clubs out of their domestic leagues as they are threatening to. This is surely just a step towards the breakaway league they want anyway, so let them go now rather than trying to cling on. Use it as an opportunity to reform the Premier League to actually benefit football in this country, even if the size of the pot is reduced.
