Most people seem to think Barzil/Ivory Coast/Portugal/Noth Korea is the group of death but I just don't see it because Brazil are just too good tio be troubled though 2nd/3rd is up for grabs.
I dunno, I don't think it's beyond the realms of possibility for Portugal to get a draw with Brazil, and if they do that, and score more against N Korea then they could finish top.
