When the group stage is finished at the World Cup on Thursday, June 28, each of the eight groups will have two teams that advance to the knockout round.
However, depending on just how things shake out in in group play, a tiebreaker may need to be used to determine which teams advance or which team won the group.
Here's a breakdown of how the World Cup tiebreaker scenarios play out for teams that are tied in points.
1. Goal difference in all group matches
2. Goals scored in all group matches
If two or more teams are still tied after using these initial tiebreakers, the next round of tiebreakers is used.
