The team that scored more goals on aggregate over the two legs advanced to the next round.
If the aggregate score was level, the away goals rule was applied, i.e. the team that scored more goals away from home over the two legs advanced.
If no goals were scored during extra time, the winners were decided by a penalty shoot-out.
In the final, which was played as a single match, if the score was level at the end of normal time, extra time would be played, followed by a penalty shoot-out if the score was still level.
[2] The mechanism of the draws for each round was as follows: For the quarter-finals and semi-finals, teams from the same city were not scheduled to play at home on the same day or consecutive days, due to logistics and crowd control.
[3] To avoid such scheduling conflict, if the two teams were drawn to play at home for the same leg, the order of legs of the tie involving the team which was not titleholders of Champions League or Europa League (or lower-tier, if both were continental titleholders), or the team with the lower domestic ranking in the qualifying season (if neither team were continental title holder) was reversed from the original draw.
[4] The schedule was as follows (all draws were held at the UEFA headquarters in Nyon, Switzerland).
