Each tie in the
knockout phase, apart from the final, was played over
two legs, with each team playing one leg at home. 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 away goals were also equal, then
extra time was played. The away goals rule was again applied after extra time, i.e. if there were goals scored during extra time and the aggregate score is still level, the visiting team advanced by more away goals scored. 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. 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. ==Schedule==
