[3] The labels in the parentheses show how each team qualified for the place of its starting round:[3][4][5] The schedule of the competition was as follows.
For the draw, the teams were seeded into six pots, in accordance with the Club Ranking, based on their performance in European competitions during a three-year period and the lowest possible position that any club from that league can occupy in the draw is calculated by adding the results of the worst performing team from each league.
There were scheduling restrictions: for example, teams from the same city in general are not scheduled to play at home on the same round (to avoid them playing at home on the same day or on consecutive days, due to logistics and crowd control).
The team that finished in the higher Top 16 place will play the first and the third (if it is necessary) legs of the series at home.
