Football leagues are in a bit of a weird position here where one league (English) being drastically stronger in pure monetary terms than the rest means the others can't really let up.

Similarly there's quite a lot of push from the most powerful teams in some of these leagues to break off and form a European Super League; with Spain's two biggest teams being the biggest backers of the project.

ETA: not agreeing with how aggressive they are exactly, but do think long term they're probably in a lot of trouble if/when money starts to properly force a European Super League into existence.
