I already knew this, doesn't change the fact that it is foot + ball, or the equivalent translation, in alot of languages. Football, or more appropriately "footie", is a better description of the sport than soccer.
Finally we have the most appropriate and favourite argument that we Brits use against Americans and other foreign English speakers; it's our fucking language, we'll speak it however we like.
Edit: Seriously, the problem with the word Soccer and the Americans calling Handegg Football is that it conjures up the idea that America loves to project - our way is better than your way. They had no need to use a word that already had a use, that was a name of the worlds most popular sport, but they did to try to lord it over everybody else.
