|Champions League Live Stream|
The UEFA Champions League (abbreviated as UCL) is an annual club football competition organised by the Union of European Football Associations (UEFA) and contested by top-division European clubs, deciding the best team in Europe.
It is one of the most prestigious tournaments in the world and the most prestigious club competition in European football, played by the national league champions (and, for some nations, one or more runners-up) of the strongest UEFA national associations.
Introduced in 1955 as the European Champion Clubs' Cup, more commonly known as the European Cup, it was initially a straight knockout tournament open only to the champion club of each national championship. The competition took on its current name in 1992, adding a round-robin group stage and allowing multiple entrants from certain countries.
It has since been expanded, and while most of Europe's national leagues can still only enter their champion, the strongest leagues now provide up to five teams.
Clubs that finish next-in-line in their national league, having not qualified for the Champions League, are eligible for the second-tier UEFA Europa League competition. (Beginning in 2021, UEFA will hold a third-tier competition called UEFA Europa League 2, which will be composed of teams not eligible for the UEFA Europa League.
