The UEFA Women's Champions League comprises a qualifying group stage, four rounds of two-legged knockout ties and a one-off final.
The lower-ranked champion clubs compete in four-team, one-venue mini-tournaments hosted by one of the competitors.
The qualifying round winners and two best runners-up 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.
The 2014/15 edition concludes at the Friedrich-Ludwig-Jahn-Sportpark in Berlin, the city which also stages the men's final.
Further details, including the criteria for separating teams that finish level on points in a group, can be found in the official competition regulations.
