Owning the biggest stadium in the country... well, it's something to shout about even if your team isn't winning any trophies.
Not that all of these even belong to clubs! Often, the largest football ground in a country is a national stadium reserved for one-off, whopping mega-matches (as Sky Sports would probably promote them).
But what each of these 20 stadiums has in common is that in their own football-mad country - from Brazil to Germany, Mexico to Spain - they are The Daddy.
All you need to do is pick out the biggest stadium against its nearest in-country rivals - then tell us your score when you're done and tag a mate in to set them the challenge. Good luck!
