[OLYMPIC GOLD-MEDAL GAME] Mexico pulled one of the greatest upsets in the history of the Olympics when it beat Brazil, 2-1, in the men's gold-medal game at Wembley Stadium. Oribe Peralta was the hero for Mexico with two goals, the first after 30 seconds. The loss kept alive Brazil's record of never having won Olympic gold and will surely lead to the firing of its coach, Mano Menezes.

Mexico coach Luis Fernando Tena said his team would need an "almost perfect" game to beat Brazil, and he got it from his team that was missing star Giovani dos Santos.

Brazil had scored scored three goals in each of its first five games but was shut out by the Tri until the first minute of stoppage time when Hulk scored. It had never looked capable of scoring on the sturdy Mexican defense anchored by goalie Jose Corona until Hulk's goal but then almost equalized when Chelsea-bound Oscar had an open header with 30 seconds to play that he was unable to put on target.

It was that kind of game for the Brazilian attack, which failed to live up to its reputation.

Brazil cracked under the pressure, conceding the quickest goal in the history of the Olympics when Manchester City right back Rafael turned the ball over, allowing Peralta to score.

A foul by Real Madrid's Marcelo set up a free kick for Perelman to make it 2-0 in the 75th minute with a open header.

Shortly thereafter, Rafael and teammate Juan started arguing with each other and had to be separated by English referee Mark Clattenburg.

"We all know that we need to win the gold," Menezes said the day before the final.

But like Romario, Ronaldo and many other Brazilian greats before them, Neymar and Co., came up short.
