Scroll through these ELO rankings and you'll see what I'm talking about. The EPL only has 6 teams in the Top 50 ranking of global clubs, while La Liga has 13 and the Bundesliga has 8.
In fact, outside of those 6 clubs, the next-highest-ranked EPL team is #62 Leicester City. There are 16 Spanish teams ranked higher than the 7th-best EPL club.
