The UEFA Champions League is an annual Association football cup competition organised by UEFA since 1955 for the top football clubs in Europe. It is the most prestigious club trophy in European football.
Europe's strongest national leagues now provide up to four teams each for the competition. The title has been won by 21 different clubs, 12 of which have won the title more than once. The all-time record-holders are Real Madrid, who have won the competition nine times, including the first five seasons it was contested. Since the tournament changed name and structure in 1992, no club has managed consecutive wins.
