I kind of understand why people like premier league as much as they do and that is really good. However looking at the last winners of champions league for example, in the last 20 years, there has been 4 winners of champions league from premier league for example, whereas real Madrid alone won it 4 times in the last 6 years alone.
I am not saying premier league is not good or La Liga is better or anything like that, but maybe we are looking at premier league with a bit of recency bias and think they have always been this good. Unfortunately for many British people, British football wasn't always this good, it has times when it is great and it has times when it is not really that great. However if we look into Serie A that is even worse, they had 3 but last one was 09-10 Inter.
