Rules for drawing lots for the Champions League 1/4 finals.

The quarter-finals of the Champions League adopt the home and away elimination system. Now the first place in each group belongs to one category, and the second place belongs to one category, so draw lots. But teams from the same country can't be drawn together, nor can teams from the same group in the group stage. But when the first place in the small group is eliminated, you can play away first. . .

One more thing, the final of 1/8 is divided into 8 groups, the champion of group A is against the champion of group B, the champion of group C is against the champion of group D, and so on, then the champion of group AB is against the champion of group CD, the champion of group EF is against the champion of group GH, and finally the champion of group ABCD and the champion of group EFGH compete for the final champion!
