All matches in the qualifying stage are played on a single-leg knockout basis.
A draw is conducted to determine the single-leg matches for each stage. The first team drawn hosts the match.
The winners of the preliminary round qualify for the round of 32. Likewise, each winner of the round of 32 qualifies for the round of 16.
The eight winners of the round of 16 qualify for the quarter-finals.
The procedures for each draw are prepared by the UEFA administration and sent to the participating clubs in due time. COVID-19 restrictions may be taken into account.
