Group C: Greece-Ivory Coast & Japan-Colombia
Advancement Scenarios:
Colombia has already clinched a spot in the knockout round and has all but clinched first place in the group. It only needs a draw with Japan, or a loss and an Ivory Coast loss or draw, to clinch the top spot in the group. The only way it can fall out of first place is with a blowout loss to Japan combined with a blowout win by the Ivory Coast over Greece, which is unlikely.
Ivory Coast will clinch a spot in the knockout round with a win over Greece, or a draw with Greece combined with a Colombia-Japan draw.
Japan will clinch a spot in the knockout round with a win over Colombia combined with an Ivory Coast loss to Greece. Japan will also move on with a win of at least two goals over Colombia combined with an Ivory Coast-Greece draw.
Greece will clinch a spot in the knockout round with a win over Ivory Coast combined with a Japan loss or draw against Colombia. Greece can also advance with a blowout win over Ivory Coast combined with a close Japan win over Colombia (for instance, it would advance with a 3-0 win over Ivory Coast combined with a 1-0 Japan win over Colombia, as it would win the goals-scored tiebreaker over Japan).
