The UEFA Champions League is one of the most prestigious club football competitions in the world. To ensure fair play and competitive balance, there are several key rules that govern the tournament. Firstly, the competition is open to top-tier clubs from European countries, with each nation allocated a certain number of spots based on their UEFA coefficient rankings. Teams must qualify through domestic league finishes or cup victories.

During the group stage, teams are divided into eight groups of four, playing home and away fixtures. Points are awarded for wins (3 points) and draws (1 point), with matches decided by goal difference if tied. Knockout stages follow, featuring round-of-16, quarter-final, semi-final, and final rounds, all played as single-elimination matches. Extra time and penalties decide tied games.

Unique rules include the away goals rule, which was abolished in 2021, and substitutions, increased to five per match during the pandemic. Fair play and sportsmanship are also emphasized, with yellow and red cards impacting team rankings. The spirit of the game remains central to the Champions League's success. 💪✨
