That’s the 2 big guys. If you’re going by population size England wins. Most English cities have total stadium capacity of about 25% of the population. And 23 home games a year. Most American cities even if ALL the sports played home games at the same time you’re looking at 2 maybe 3% of the populations.
Of course here in the US we have the high school football stadiums, that do rival some of the English soccer stadiums, especially here in Texas.
That’s a good point about percent of population
