Given that "football" (soccer to you), much though I despise it, is the most popular sport in most of the World, it seems churlish for you to use the term to mean a completely different (US) game. For the record, there are many different types of football, including Association Football (a.k.a. soccer), Rugby Union, Australian Rules, American, Rugby league and doubtless several others. None, in my view, have the right to reserve the term "football" to themselves.
