10 games so far, 7 have had outright winners, the other 3 being draws.
Of the 7 wins, 6 of the winners qualified for the WC before or at the same time as the loser. Perhaps not suprising, since there should be a strong correlation between strength of team and speed of qualification. But interesting that, at kickoff time in several of these games, the eventual winner was not the favourite (South Korea,Japan, Ghana, Slovenia).
Korea qualified before Greece
Argentina qualified on the same day as Nigeria
Slovenia qualified on the same day as Algeria
Ghana qualified before Serbia
Germany qualified after AustraliaNetherlands qualified before Denmark
Japan qualified before Cameroon
So using that this as a prediction technique for the remaining opening matches, Paraguay should beat Italy...halftime score is 1-0
