UEFA Conference League in the context of "Russian Premier League"

The UEFA Champions League (UCL), usually known simply as the Champions League, is an annual club association football competition organised by the Union of European Football Associations (UEFA) that is contested by top-division European clubs. The competition begins with a round robin league phase to qualify for the double-legged knockout rounds, and a single-leg final. It is the most-watched club competition in the world and the third most-watched football competition overall, behind only the FIFA World Cup and the UEFA European Championship. It is one of the most prestigious football 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 their national associations.

Introduced in 1955 as the European Champion Clubs' Cup (French: Coupe des Clubs Champions Européens), and commonly known as the European Cup, it was initially a straight knockout tournament open only to the champions of Europe's domestic leagues, with its winner reckoned as the European club champion. The competition took on its current name in 1992, adding a round-robin group stage in 1991 and allowing multiple entrants from certain countries since the 1997–98 season. While only the winners of many of Europe's national leagues can enter the competition, the top 5 leagues by coefficient provide four teams each by default, with a possibility for additional spots based on performance during the previous season. Clubs that finish below the qualifying spots are eligible for the second-tier UEFA Europa League competition, and since 2021, for the third-tier UEFA Conference League.

The UEFA Europa League (UEL), usually known simply as the Europa League, is an annual club football competition organised since 1971 by the Union of European Football Associations (UEFA) for eligible European football clubs. It is the second-tier competition of European club football, ranking below the UEFA Champions League and above the UEFA Conference League.

Introduced in 1971 as the UEFA Cup, it replaced the Inter-Cities Fairs Cup. From the 2004–05 season a group stage was added before the knockout phase. The competition took on its current name in 2009, following a change in format. The 2009 re-branding included a merge with the UEFA Intertoto Cup, producing an enlarged competition format, with an expanded group stage and a change in qualifying criteria. In the 2024–25 season, the group stage was replaced with an expanded league phase of 36 teams.

The Union of European Football Associations (UEFA /juːˈeɪfə/ yoo-AY-fə; French: Union des associations européennes de football; German: Union der europäischen Fußballverbände) is one of six continental bodies of governance in association football. It governs football, futsal and beach football in Europe and the transcontinental countries of Turkey, Azerbaijan, Georgia and Kazakhstan, as well as the West Asian countries of Cyprus, Armenia and Israel. UEFA consists of 55 national association members. Since 2022, due to the Russian invasion of Ukraine, FIFA and UEFA suspended all Russian national teams and clubs from any FIFA and UEFA competitions.UEFA consists of the national football associations of Europe, and runs national and club competitions including the European Championship, Nations League, Champions League, Europa League, Conference League, and Super Cup, and also controls the prize money, regulations, as well as media rights to those competitions.

Henri Delaunay acted as the first general secretary and Ebbe Schwartz as the first president. The current president is Aleksander Čeferin, a former Football Association of Slovenia president, who was elected as UEFA's seventh president at the 12th Extraordinary UEFA Congress in Athens in September 2016, and automatically became a vice-president of the world body FIFA.
