No, it really is their problem. It's not like we're using unnecessarily complex language as a method of obfuscation – this is the official name for the sport, comprising two words that should be readily familiar to the vast majority of readers, with a fuller explanation a single click of the mouse away (plus another click to get back). "Association football" on the first instance and "football" thereafter (or "soccer" if the tournament is held in a country where that is the common name) should be sufficient. – Jay
