According to the competition system of the new AFC Champions League, East Asia and West Asia are divided into four groups, with 32 teams in eight groups. The top two finishers in each group form the top team of 16, and then East Asia and West Asia play the knockout rounds of 16 into 8 respectively, and finally decide the quarter-finals of the AFC Champions League. These eight teams will draw lots for two more rounds. It is worth mentioning that in the match of 16 into 8, there were not two rounds of home and away matches as usual, but a knockout match was held directly at the home of the first place in the group. For example, if Group A comes against Group B first, then the knockout will be held directly at the home of the team with the first place in Group A, so the competition for the first place in the group will be fierce.
