Format
Each tie, apart from the preliminary round, 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 at the end of normal time of the second leg, extra time was played, and if the same number of goals were scored by both teams during extra time, the tie was decided by a penalty shoot-out.

In the preliminary round, the semi-finals and final were played as a single match hosted by one of the participating teams. If the score was level at the end of normal time, extra time was played, and if the same number of goals were scored by both teams during extra time, the tie was decided by a penalty shoot-out.

The video assistant referee (VAR) was used in the third qualifying round and the play-off round.

In the draws for each round, teams were seeded based on their UEFA club coefficients at the beginning of the season, with the teams divided into seeded and unseeded pots containing the same number of teams. A seeded team was drawn against an unseeded team, with the order of legs (or the administrative "home" team in the preliminary round matches) in each tie decided by draw. As the identity of the winners of the previous round were not known at the time of the draws, the seeding was carried out under the assumption that the team with the higher coefficient of an undecided tie advanced to the subsequent round, which meant if the team with the lower coefficient was to advance, it would simply take the seeding of its opponent. Prior to the draws, UEFA could form "groups" in accordance with the principles set by the Club Competitions Committee purely for the convenience of the draw and not to resemble any real groupings in the sense of the competition. Teams from associations with political conflicts as decided by UEFA could not be drawn into the same tie. After the draws, the order of legs of a tie could be reversed by UEFA due to scheduling or venue conflicts.

The same applied for the final draw, between the two winners of the semi-finals, whose identity was not known at the time of draw.
