GROUP G
- England and Belgium have qualified and have identical records going into their final match.
- If they draw then the top two positions will be decided by the number of cards accumulated. England have two yellows and Belgium have picked up three.
- If both teams have the same number of booking points then lots will be drawn to decide the final positions.
Remaining fixtures on Thursday:
England v Belgium - 20:00
Panama v Tunisia - 20:00
GROUP H
- Japan and Senegal require only a point in their respective games against Poland and Colombia to qualify.
- Colombia will qualify with victory over Senegal. If Colombia win Japan will need to lose by fewer goals than Senegal to progress.
- Colombia can also qualify with a draw if Japan lose, because they have a better goal difference.
Remaining fixtures on Thursday:
Japan v Poland - 16:00
Senegal v Colombia - 16:00
