Mexico and Japan look fairly evenly matched, and with the winner of their 2012 Olympic football semifinal guaranteed a medal (and a probable match against a star-studded, albeit erratic, Brazil side) expect a semifinal in the vein of yesterday's super match between Canada and the United States in the women's tournament. Japan already have a major scalp in this tournament, beating Spain in their opening game, and they looked very convincing against Egypt in the quarterfinals. Mexico struggled against Senegal, so the momentum is clearly with Japan. That said, there's so much quality in this El Tri side that it's not difficult at all to picture them progressing here.
Japan starting lineup (4-4-2): Shuichi Gonda; Yuhel Tokunaga, Hiroki Sakai, Daisuke Suzuki, Maya Yoshida; Takahiro Ohgihara, Hotaru Yamaguchi, Keigo Higashi, Hiroshi Kiyotake; Yuki Otsu, Kensuke Nagai.
