Regular season
The 32 teams are drawn into eight groups of four. In each group, teams play against each other home-and-away in a round-robin format. The group winners and runners-up advance to the last 16, while the third-placed teams and fourth-placed teams are eliminated.

 * 2) Head-to-head point differential.
 * 3) Point differential during the regular season.
 * 4) Points scored during the regular season.
 * 5) Sum of quotients of points scored and points allowed in each regular season match.

Last 16
