Champions League scoring rules
After 90 minutes of the second round, if the total score is tied, those who score away from home will advance to the next round; If the away goal is the same, it will enter overtime, and overtime also has the advantage of away goal. This rule is too obvious for the visiting team in the second round. After the away goal is cancelled, both sides will attack more freely. If the scores of the two rounds are the same, 30 minutes of overtime will be played, and if the outcome is still undecided, a penalty shootout will be held.
