The UEFA Champions League (usually referred to as simply the Champions League or less frequently as the European Cup) is an annual 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.
Prior to 1992 the tournament was officially called the European Champion Clubs’ Cup but was usually referred to as simply the European Cup or European Champions’ Cup. The competition was initially a straight knockout competition open only to the champion club of each country. During the 1990s the tournament began to be expanded, incorporating a round-robin group phase and more teams. Europe’s strongest national leagues now provide up to four teams each for the competition.
