Introduction of champions league

The European Champions League, referred to as the "Champions League" or "Champions League", is an annual football competition sponsored by the European Football Association Federation, which represents the highest level and honor of European club football and is recognized as the most influential and highest level club event in the world.

The Champions League is one of the most awarded football and sports events in the world. The UEFA Champions League was formerly known as the UEFA Champions Club Cup in 1954, and was renamed in 1992.

2. The birth of the Champions League

After the end of World War II, football has been fully revived all over the world, but there are few exchanges between national teams and competitions between clubs. At that time, Gabriel Yano, the founder of the European Footballer of the Year award, put forward the idea of creating the European Club Cup, aiming at making the top European clubs compete on the same stage.

The plan was warmly welcomed by several clubs, such as Real Madrid, Anderlecht and Fast Vienna, and the Hungarian Football Association.
