They are, like Germany of Soccer - somehow manages to raise their game under pressure. Regarding this WC, you missed my full quote, let's refresh it

: "If any team is to win the WC, they'll have to beat Aussies in a KO game". Poms were just a little better team, playing at home - no shame in that for Aussies, they are the toughest nut to crack, but sometimes they'll also miss-out, like Germany did this time ... that too after losing against the Mex & Koreans!!!
Indeed this is the weakest Aussie team since 1983 ('87 was a brilliant team, just too young to enter WC as "star") - still this Aussie team made the KO as first team, and lost the SF to the eventual winners.
