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 participants.
The qualifying round winners join the teams given a bye past that stage in the round of 32. From here on the competition consists of two-legged knockout ties, continuing with the round of 16, 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 on 1 June at Cardiff City Stadium, two days before the men's final at the National Stadium of Wales.
Further details, including the criteria for separating teams that finish level on points in a group, can be found in the official competition regulations.
The launch of the UEFA Women's Champions League for the 2009/10 season also meant a fresh trophy to replace the previous UEFA Women's Cup.
The trophy is 60cm in height, 10kg in weight and made of sterling silver. The spiralling arms and the central body provide a vision of dynamism and strength. The column in the middle will be etched with the names of the winners, representing the climb to the top of European women's club football.
The original trophy, which is used for the official presentation ceremony at the final, remains in UEFA's keeping at all times. A full-size replica UEFA Women’s Champions League winners' trophy is awarded to the winning club as well as 35 gold medals, while 35 silver medals are presented to the runners-up.
Any club that wins the competition three consecutive times or five times in total receives a special mark of recognition. Once a cycle of three successive victories or five in total has been completed, the club concerned starts a new cycle from zero.
