I've recently been to London and made the small autistic effort of counting football shirts. Though I didn't count groups, so two obvious brothers wearing shirts of one club counted as one
I only kept up with the London club shirts and ended up with Arsenal at 11, Chelsea at 8, and Tottenham at 1. West Ham at 0, despite me staying in Tower Hamlets near the Olympic Park and going past a West Ham pub regularly. I saw two guys with Millwall merch, but no shirts
Anyway, the amount of PSG and Real shirts definitely was on par with Arsenal and Chelsea, but I didn't count. No idea how many people were tourists, of course
Also, I just wanna say that one of the first things I saw after stepping out of the very diverse tube was a group of like 20 Paki/Bangladeshi Muslims walking past me in full religious garments. And the next thing I saw was an ad for a campaign against human trafficking and arranged marriages. Not that this is a unique feature in major western cities
