The tournament will open with a group stage consisting of 16 groups of three teams, with the top two teams progressing from each group to a knockout tournament starting with a round of 32 teams.[14] The number of games played overall will increase from 64 to 80, but the number of games played by finalists remains at seven, the same as with 32 teams, except that one group match will be replaced by a knockout match. The tournament will also be completed within 32 days, same as previous 32-team tournaments.[15]
