Seedings The 24 teams were divided into six pots of four teams, with a team from each pot being drawn to each group. Teams from the same country could not be drawn into the same group.

Goal difference in matches among tied teams; •
Away goals scored in matches among tied teams; • Goal difference in all group matches; • Goals scored in all group matches; • If more than two teams were tied, and after applying all head-to-head criteria above, a subset of teams were still tied, all head-to-head criteria above were reapplied exclusively to this subset of teams; • Drawing lots.
