It doesn’t really matter if you call it football or soccer, they both mean the same thing. Football is universal as almost everyone loves football and almost everyone has their favorite team.
It doesn’t matter if your from Europe where you have all the big premier and European league teams or you are from South America where they a long tradition of playing football, especially at the national level. Africa as well are starting to make an impact on the international scene.
The USA of course have their own version of the game which is a sort of cross between football or soccer as they call it and rugby plus they are preoccupied with other National sports like baseball and basketball, with the result that football or soccer is not as popular in the US as elsewhere but never the less there is still a loyal fan base in the USA.
