I'm starting to wish there was a "specialized knowledge" category to quarantine/ignore grids like this, for those of us who won't enjoy a one-note grid on a mastermind level of topic detail.

Nobody without a granular interest in football would go beyond "these are all stadia", and it's just no fun to repeat the same thing for an entire grid.

I have absolutely no interest in football but still managed to find 2 groups. There's nothing wrong with themed walls. Remember it's only a game PUZZLED. If you don't like the content
then try a different wall.

You're screwed unless you're a major football geek
