2021–22 UEFA Champions League qualifying phase and play-off round
A total of 32 teams played in the first qualifying round: 31 teams which entered in this round, and 1 winner of the preliminary round. Seeding of teams was based on their 2021 UEFA club coefficients. For the winner of the preliminary round, whose identity was not known at the time of draw, the club coefficient of the highest-ranked remaining team was used. Prior to the draw, UEFA formed four groups of four seeded teams and four unseeded teams in accordance with the principles set by the Club Competitions Committee. The first team drawn in each tie would be the home team of the first leg.
