For the draw, the teams were seeded into 10 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.
The fixtures were decided after the draw, using a computer draw not shown to public, with the following match sequence: Note: Positions for scheduling do not use the seeding pots, e.g., Team 1 is not necessarily the team from Pot 1 in the draw.
