It's also incredibly easy to both pick a few isolated moments of English arrogance from the vast number of English media outlets and to understand it, given the prevalence of English speakers/readers around the world.
This is an interesting counter showing how, just maybe, it's not really an isolated thing for the English: https://www.theguardian.com/football/2018/jul/12/england-unbelievably-inferior-croatia-press-world-cup-semi-final
The ignorance there is breathtaking. All of that would be true....about 20 years ago.
In fairness, we're not popular abroad generally, are we? If you see most of the comments sections on the Guardian throughout the WC, there's been lots of people from other countries saying how shit we are, saying how much we overrate ourselves, arrogance etc etc
I think pictures of English fans celebrating and throwing lager around have probably been transmitted around the world, and possibly given a slightly false impression.
Obviously, you get a few people getting carried away with the nationalism and all that (as with any country), but I do think it's been different this time. People had low expectations, they like the manager and what he was trying to do, and they respected the effort of a limited group of players, who were a Harry Kane finish away from probably getting to the final.
