The ranking of teams was determined as follows: • 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 are tied and they met in the last round of the group; • Disciplinary points (yellow card = 1 point, red card as a result of two yellow cards = 3 points, direct red card = 3 points, yellow card followed by direct red card = 4 points); • Drawing of lots. ==First preliminary round==
