The UEFA Champions League is back! The group stage of the 2023-24 campaign kicks off Tuesday, with 32 teams vying to win club soccer's ultimate prize.

Each club plays two games (home and away) against the other three teams in their group, with match days scheduled into mid-December. The top two in each group advances to the Round of 16 (February/March), with the final scheduled for June 1 at London's Wembley Stadium.

Reigning champion Manchester City is the odds-on favorite – having also won back-to-back Premier League titles – and their championship defense begins Tuesday at home against Red Star Belgrade.
