The UEFA Champions League is an annual continental club football competition organized by the UEFA and contests by the top-division European clubs. It's considered one of the most prestigious club competitions in the European football, played by the national league champions of the strongest UEFA national associations. The competition was formally added into FIFA 19, marking it's first appearance in the game series.
In its current format, the league begins in late June with four knockout qualifying rounds and a play-off round. The 6 surviving teams enter the group stage, joining 26 teams qualified in advance. The 32 teams are drawn into eight groups of four teams and play each other in a double round-robin system. The eight group winners and eight runners-up proceed to the knockout phase that culminates with the final match in May. The winner of the UEFA Champions League qualifies for the UEFA Super Cup and the FIFA Club World Cup.
