In the group stage, teams are ranked according to points (3 points for a win, 1 point for a draw, 0 points for a loss), and if tied on points, the following tiebreaking criteria are applied, in the order given, to determine the rankings (Regulations Articles 18.01 and 18.02):
Goals scored in head-to-head matches among tied teams;
If more than two teams are tied, and after applying all head-to-head criteria above, a subset of teams are still tied, all head-to-head criteria above are reapplied exclusively to this subset of teams;
Goal difference in all group matches;
Goals scored in all group matches;
Penalty shoot-out if only two teams have the same number of points, and they met in the last round of the group and are tied after applying all criteria above (not used if more than two teams have the same number of points, or if their rankings are not relevant for qualification for the next stage);
Disciplinary points (red card = 3 points, yellow card = 1 point, expulsion for two yellow cards in one match = 3 points);
