The big teams are up against average competition, but don't assume they'll win easily. Spain, Great Britain and Uruguay did not live up to expectations in their first games.

Spain are stunningly in a near must-win situation on the second day of the London 2012 Olympics men's football tournament, while many of the tournament's other favorites will be looking to lock up semifinal berths. Brazil play an early match against a very tough Belarus team just before Uruguay take on Senegal in the best of the mid-afternoon games. Both Spain and hosts Great Britain play during the late timeslot, and both will be heavy favorites in their games. Neither looked great in their first match, though, and is unlikely to have a complete walkover.
