In Germany and in some European countries. Similar situation to JJ.
They are still levels below in popularity to prem clubs.
You guys live in a Eurocentric region. EPL clubs reign supreme outside Europe.
Bayern do have a massive following in the US, I think it comes from the millions of German-Americans. Something like 40+ mio Americans have German ancestry.
Anyway, I fully agree with you that the English clubs have a bigger world appeal compared to most European clubs located in Spain, Germany and Italy.
This is not fully related, but still is somehow - colonies, colonies, colonies. The English brought their influence all over the world, Spain did so too a smaller extend.
South America is La Liga territory because of all those countries bar Brazil being former Spanish colonies, then you got Mexico as well. And Portugueese and Spanish is so heavily linked that Brazil is still a big pond for Real Madrid and Barca, history also shows that with the great players they had from there.
The PL is so massively popular because of English being the lingua franca. Anyone who speaks English no matter if he/she is from Ghana, Kenya, India, Australia, China, the US and so on can easily follow their league because of this. And they just been way better to place themselves in a good marketing position, it started with the introduction of the PL back in the early 90's. Then it really gained ground in the early 00's.
Germany and Italy are big countries with a lot of influence in Europe. Which means both Bayern and Juventus will have a huge following in Europe.
But as these two countries never had a huge influence in far away corners of the world, they couldn't/didn't set a culture mark there. Germany and Italy did have colonies, but it was in such a short time span that it didn't matter much in world history and they were too few compared to Britain, Spain, France etc.
Speaking of France, Ligue 1 could have a great product with all the French speaking countries in Africa. They never capitalized on that.
Bayern Munich and Juventus are huge clubs in their own right, but Italian and German is not huge world wide languages, but in stead have lots of influence in Europa. This is no doubt making it harder for them to challenge the PL monopoly.
