How about this for a crazy, but possible, scenario in Group C:

Slovenia 2-2 England
USA 0-0 Algeria

Slovenia would advance as the group's first place team with 5 points

England & USA would be tied on points (3), goal difference (0), goals scored (3), and head-to-head (1-1). A coin would be flipped to determine who would advance as the group's second place team.

Of course, the USA & England can avoid such a mess and insure their advancement by winning their respective games on Wednesday.
