Matches later today (2 ET):
Switzerland vs. Costa Rica
Serbia vs. Brazil
As it stands currently, Brazil and Switzerland will advance. If Serbia can pull an upset, they'll advance. Plenty of intrigue.
Also, with a stunning 2-0 loss to South Korea this morning, Germany has failed to advance past the group stage for the first time ever. Sweden wins the group, with Mexico advancing in 2nd place despite being pasted 3-0 by Sweden today.
