To add to what I wrote above, there are past brazilian stars like Ricardo, Rai, and Leonardo that are always linked to PSG, and some of them are very vocal like Rai, or Leonardo that do a lot of lobbying for them in Brazil.Yeah, but there's always also a bunch of Germans at Arsenal and I never got a hard on for them.
If you set foot in Brazil even before the Qatar era, it was not that hard to meet people with a PSG shirt.
