The UEFA Champions League is the blue riband competition of European club football.
Formerly called the European Cup (from 1955-56 to 1991-92), the UEFA Champions League has been graced by 141 different clubs from 33 UEFA member associations.
In 2003-04, the Champions League did away with the second group stage and has since featured three two-legged knockout rounds - Round of 16 comprising the eight group winners and runner-ups, four quarterfinals and two semifinals, before a one-off final.
In 28 editions of the competition, Real Madrid (23 consecutive) and Barcelona of Spain have each have made a record 24 appearances, followed by 23 appearances apiece by Bayern Munich of Germany and Porto of Portugal, 22 by Manchester United of England and 20 by Juventus of Italy.
Atalanta of Italy, the competition debutantes in 2019-20, are one of 50 clubs to have made exactly one appearance in the group stage of the Champions League.
With seven titles, Real Madrid lead a group of 14 clubs to have won the competition in its present format. With 13 titles, Real are also the most successful club overall in the European Cup / UEFA Champions League.
Perhaps not surprisingly, the Spanish capital club have played the most matches (260), have the most match wins (155) and have scored the most goals (551) in the Champions League. Three of the competition's five most prolific scorers have donned the Real Madrid jersey.
