Qualifying round
The 32 lower-ranked champion clubs compete in eight four-team, one-venue mini-tournaments hosted by one of the competitors. The top team from each group progresses along with the two best runners-up.
Knockout phase
The qualifying round winners join the teams given a bye past that stage in the round of 32. From hereon the competition consists of two-legged knockout ties, continuing with the round of 16, which is drawn along with the last 32. The draw for the remainder of the competition is then made, with quarter-finals and semi-finals played over two legs. If scores are level after 90 or 120 minutes of the second leg, the team with the most away goals wins, otherwise a penalty shoot-out is held.
Final
The final is a one-off match held two nights before the men's UEFA Champions League final in the same city. The 2011/12 competition concludes in Munich on Thursday 17 May and the 2012/13 edition in London.
Further details, including the criteria for separating teams that finish level on points in a group, can be found in the official competition regulations.
