Tie-breaking criteria

If two or more teams are equal on points on completion of the group matches, the following criteria are applied to determine the rankings:^[31]

1. Higher number of points obtained in the matches played between the teams in question;
2. Superior goal difference resulting from the matches played between the teams in question (if more than two teams finish equal on points);
3. Higher number of goals scored in the matches played between the teams in question (if more than two teams finish equal on points);
4. If, after having applied criteria 1) to 3), two teams still have an equal ranking, criteria 1) to 3) are reapplied exclusively to the matches between the two teams in question to determine the final rankings of the two teams. If this procedure does not lead to a decision, criteria 5) to 9) apply in the order given;^[32]
5. superior goal difference in all group matches;
6. higher number of goals scored in all group matches;
7. position in the UEFA national team coefficient ranking system
8. fair play conduct of the teams (final tournament);
9. drawing of lots

Note: As all teams have different UEFA national team coefficient, the last two tie-breakers (i.e. fair play conduct and drawing of lots) will never be applied in this tournament.
