Very telling how the article ends with a snippet about how the previous season had record-breaking revenues and how La Liga is one of the most profitable sports competitions in the world. It is never enough.
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.
