Neither, there is too much hype around Brazil at the moment who recently haven;t been playing there best, there diamond 5 or w/e it is isn't as strong as people make them out as Brazil have a relatively weak defence. Australia are in a relatively tough group, i can't see them winning but if things go there way results wise then they'll definetly reach the second round.
In the match though 2-0 Brazil
I'd love to say England FTW, but in all honesty me reckons Argentina..
