bcubed And why do FIFA tinker with stuff just before major tournaments anyway? We think we know the normal rules and interpretation and they always come up with something to confuse us.
Because "our" normal rules and interpretation are probably quite different from the normal rules and interpretation they have in South America or Asia - the rules might be universal, but the interpretations certainly aren't.
They're trying to find a common ground that works for everyone - and inevitably come up with a compromise that is strange for everyone.
