Which football teams will battle for the bronze medal this Friday, and which will contend for the gold medal on Saturday? Today's semifinals separated the Olympic cream from the crop. Here's what happened.

Mexico vs. Japan

Mexico gained a solid 3-1 win over Japan in today's Wembley Park semifinal. Japan certainly had a strong start; Yuki Otsu scored within the first 12 minutes and joyfully leapt into the arms of his teammates. (It's hard not to like Yuki Otsu.) Unfortunately for the Japanese, their team couldn't keep the momentum going. Mexico followed up with goals from Marco Fabian, Oribe Peralta and Javier Cortez, securing Mexico's spot in Saturday's gold medal game.

Brazil vs. South Korea

Brazil wasn't content to just beat South Korea in Manchester's Old Trafford today. Brazil trounced the Koreans 3-0, establishing themselves as undeniable gold medal contenders. Romulo Borges Monteiro scored the first goal for Brazil, followed by teammate Leandro Damiao Da Silva Dos Santos with the final two. All in all, it was a terrific game by Brazil, from the fancy footwork to Leandro Damiao's sassy little finger-wagging celebrations.

Mexico and Brazil are now both guaranteed medals in the 2012 London Olympics. At this point, it's just a matter of who will take silver and who will go home with the coveted gold. They'll play for the gold medal this Saturday, August 11, at Wembley Stadium.

South Korea and Japan will fight for the remaining bronze medal on Friday, August 10, at Cardiff's Millennium Stadium. There's still a chance for one of these teams to join Mexico and Brazil on the Olympic podium. Tune in this weekend to find out what happens.
