Earlier quoted context omitted.
It's 'football' in the UK, but in most of the rest of the Anglophone world, it's 'soccer'. Australia has its own 'football', as does Ireland.
Oddly in most of Europe it's 'football' as well, EUFA, IFA, Ligue de Football and so on, seems to be quite fractured depending on whereabouts in the world you are, and with the rise in people learning American English through TV/movies/etc I can see it becoming more popular to call it soccer.
