Tournament origins
The UEFA Champions League is open to each national association's domestic champions, as well as clubs who finish just behind them in the domestic championship table.
The first European Champions Clubs' Cup fixture was played in Lisbon and Sporting Clube de Portugal were held to a 3-3 draw by FK Partizan. The Yugoslav side won the return leg in Belgrade 5-2 to advance to the next round.
Madrid dominate
Real Madrid CF immediately made the tournament their own by winning the first five finals. Since then, other clubs have also enjoyed fruitful runs in the competition with AFC Ajax and FC Bayern München both completing three consecutive wins. However, no one club has been able to claim long-term domination.
Liverpool success
Liverpool FC's four victories between 1977 and 1984 deserve special mention as the English club won its four trophies with essentially different teams. The Reds' European pedigree shone brightly again in 2005 when they battled back from 3-0 down to defeat AC Milan on penalties.
Honours list
Real Madrid CF and AC Milan have been the most successful sides in the UEFA Champions League, winning the competition three times. Madrid are also the most successful side overall with nine triumphs, followed by seven for Milan, five for Liverpool and four each for Bayern and Ajax.
Competition change
The major turning point in the evolution of the competition came in the 1992/93 season when the UEFA Champions League, involving a group stage in addition to the traditional knockout elements, was officially inaugurated after a pilot round robin during the previous season.
