What prevents us from conducting a draw and creating a bracket as the administrator suggests, for example: A1 - C2 D1 - B2 C1 - A2 B1 - D2 The top 2 teams from groups where the outcome is clear can start their 1/4 matches, and for the rest, an ODD (one-day delay) can be scheduled for the following week, with the following week included in the time frame given for the first match of the quarter-finals. If the ODD is ignored, the team will be disqualified. The uncertainty in the schedule of group matches is largely due to the fact that players contact their opponents themselves, and there are no time limits for a single game in the group. If the bracket was initially created as, for example, in Facebook, it would be easier to record the results after each round. As it is, we need to be understanding and, first of all, in the group where there were substitutions.
