For me, it's the way lots of modern day fans will support players before teams. The amount of videos you see on YouTube or other social media platforms where there's endless compilations or tributes to these players, with shitty repetitive music played over the top..it's staggering. There's this weird fandom that is utterly obsessed with Ronaldo, Messi, Mbappe, Vinicius Jr that I find really hard to stomach at times. I think we're going to see more and more fans slip in this direction as time goes by. Social media is also making this worse with the amount of coverage these guys get, and then there's the reaction videos, the interactions, etc. It's becoming less and less about what is happening for those 90 minutes when two teams take it to the field.
I would also say the over-analysis that can be done at half time or full time, too. It feels like there's 5 hours or so that gets dedicated to a match, and the game is only a very, very small part of it. Every little thing gets blown up and has a subtext to it. It's a lot more humbling when you're actually at a stadium and you can't hear any commentary, or any half time analysis or endless replays over incidents. For me, that's the purest form of the game.
