1) Argentina 3 – 0 Brazil, Olympics 2008, Beijing
Argentina’s revenge came at last in this semi-final, and they went on to win the gold medal. Billed as the showdown between Lionel Messi and Ronaldinho, it was a young Sergio Aguero who stole the show. Brazil hadn’t conceded a single goal on the way to the semi, but Aguero found space to head/shoulder the ball home in the first half. His second came from a simple square ball across the box, and Riquelme added a third from a penalty after Aguero was fouled.
