The qualifying competition consists of three rounds: •
Preliminary round: The 26 lowest-ranked teams are drawn into five groups of four teams and two groups of three teams. Each group is played in single round-robin format at one of the teams which were pre-selected as hosts. The seven group winners advance to the main round. •
Main round: The 28 teams (21 highest-ranked teams and seven preliminary round qualifiers) are drawn into seven groups of four teams. Each group is played in single round-robin format at one of the teams which were pre-selected as hosts. The seven group winners qualify for the final tournament, while the seven runners-up and the best third-placed team advanced to the play-offs. •
Play-offs: The eight teams are drawn into four ties to play home-and-away two-legged matches to determine the last four qualified teams.
Tiebreakers In the preliminary round and main round, 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 14.01 and 14.02): • Points in head-to-head matches among tied teams; •
Goal difference in head-to-head matches among tied teams; • 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); • UEFA coefficient; • Drawing of lots. To determine the best third-placed team from the main round, the following criteria are applied (Regulations Article 15.01): • Points; • Goal difference; • Goals scored; • Disciplinary points; • UEFA coefficient; • Drawing of lots. In the play-offs, the team that scores more goals on aggregate over the two legs qualifies for the final tournament. If the aggregate score is level, the
away goals rule is applied, i.e., the team that scores more goals away from home over the two legs advances. If away goals are also equal,
extra time is played. The away goals rule is again applied after extra time, i.e., if there are goals scored during extra time and the aggregate score is still level, the visiting team advances by virtue of more away goals scored. If no goals are scored during extra time, the tie is decided by
penalty shoot-out (Regulations Article 20.01). ==Schedule==
