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 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 final is a one-off match held two nights before the men's UEFA Champions League final in the same city. The 2013/14 edition concludes in Lisbon.
Further details, including the criteria for separating teams that finish level on points in a group, can be found in the official competition regulations.

• Not far north of the Thames in west London, the stadium served London Athletics Club from 1877 until 1905 when Chelsea FC were founded, immediately joining the Football League.
• Used for the FA Cup finals of 1920, 1921 and 1922 prior to the opening of Wembley Stadium, Stamford Bridge has also hosted three senior England matches and in 1945 more than 100,000 people are thought to have watched a 3-3 friendly draw between Chelsea and post-war tourists FC Dinamo Moskva.
• Stamford Bridge staged the first leg of the inaugural Inter-Cities Fairs Cup final on 5 March 1958, a London XI holding FC Barcelona 2-2 before losing 6-0 in the return.
• Other sports held at Stamford Bridge include rugby union, athletics, shinty, speedway, greyhound racing, cricket, baseball and American football.
• The huge and costly East Stand was built in 1973 with the rest of the stadium made all-seater in the 1990s after the ground was saved from redevelopment. Reconstruction meant the demolition of the famous Shed End but also the removal of the old track which had left some stands far from the action. A major office and hotel development was also part of this rebuilding process.
• Stamford Bridge will host a second European final when the UEFA Women's Champions League concludes there on 23 May 2013.
