And there is revenue sharing amongst the 20 PL clubs. I remember one of the newly promoted PL teams involved in the Championship playoffs playing for like nearly a $200 million increase. If I recall correctly, the La Liga revenue distribution is more heavily skewed toward Barcelona and Real Madrid. Barca, RM and Bayern Munich of course are on the level economics-wise of the top Premier League clubs.
But at some point you've got to follow the money.
