The order of the Champions League and AFC Champions League group matches is the same, 1-2-3-3-2-1. The third and fourth rounds are so-called back-to-back, and the same opponents are switched home and away. The schedule is planned in advance, and the next second round of matches is not based on the previous rankings.

It is extremely important for the competition between teams that are close in strength in the third and fourth rounds.

In fact, in the group stage that implements a double cycle of home and away games, the opportunities are equal, with three home games and three away games. It's just that some teams will take advantage in the last round against teams that qualify early.
