Following the recommendation of the UEFA Club Competitions Committee and the UEFA Women’s Football Committee, the UEFA Executive Committee has today approved a proposal to remove the so-called away goals rule from all UEFA club competitions (men, women and youth) as of the qualifying phases of the 2021/22 competitions.
The away goals rule was applied to determine the winner of a two-legged knockout tie in cases where the two teams had scored the same number of goals on aggregate over the two matches. In such cases, the team which had scored the higher number of goals away from home was considered the winner of the tie and qualified for the next round of the competition. If the two teams had scored the same number of goals at home and away at the end of normal playing time in the second leg, extra time was played, followed by kicks from the penalty mark if no goal was scored.
⚽ The away goals rule will be removed from all UEFA club competitions from the 2021/22 season.

Ties in which the two teams score the same number of goals over the two legs will now have two 15-minute periods of extra time, and, if required, penalty kicks.#UCL #UWCL #UEL #UYL
With the decision to remove this rule, ties in which the two teams score the same number of goals over the two legs would be not decided on the number of goals scored away, but two 15-minute periods of extra time are played at the end of the second leg and in case the teams score the same number of goals or no goals during this extra time, kicks from the penalty mark would determine the team which qualifies to the next stage of the competition.
Since away goals would no longer be given additional weight to decide a tie, they would also be removed from the criteria used to determine the rankings when two or more teams are equal on points in the group stage i.e. the criteria applied to matches played by the teams in question. They would not be removed from the additional criteria applied to all group matches if the teams remain equal (higher number of away goals scored in all group matches), in order to retain a maximum number of sporting criteria.
