Argentina defeated Australia in the round of 16. Last time Australia made it to the round of 16 was 2006, where they were defeated with a late penalty by Italy, who went on to win the tournament. By the law established in that singular example, Argentina having defeated Australia in the round of 16 *this* time around will win the cup.
