Ah - no - football is probably the only game in which any team can be one of the best of 220 rather than best of 9 or 10! Your soccer players really are getting quite good.

Actually I think you are right about the Aussies being the world's greatest sporting nation - and now that you are even getting good at football you've got the world conquered. (Well apart from the sports only Americans play!!)
