Key Guide Takeaways
- The Champions League features 36 clubs competing in one single league table.

- The top 8 qualify directly for the Round of 16; positions 9 to 24 contest a two-legged playoff.
- Teams finishing 25th or lower are completely eliminated without Europa League safety nets.
- Away goals remain abolished; extra time and penalties decide ties level on aggregate.
The New 36-Team Single League Phase Explained
Starting from the 2024-25 season, UEFA enacted the most radical format overhaul in Champions League history, replacing the traditional eight groups of four with a single 36-club league table.
Instead of playing three opponents home and away, each participating team now plays eight matches against eight different opponents—four at home and four away—accumulating points in one unified table.
The Four Pots: How Your 8 Opponents Are Drawn
Clubs are seeded across four pots of nine teams based on their five-year UEFA coefficient. Every club, regardless of whether they are in Pot 1 or Pot 4, is drawn against two opponents from each of the four pots (one at home, one away).
This guarantees marquee heavyweight clashes between elite Pot 1 teams right from the opening matchweeks in autumn, eliminating meaningless dead-rubber group matches.
Top 8 vs. Positions 9-24: The Knockout Playoff Round
After all eight league matches are completed, progression is determined by standings in the 36-team table:
- Positions 1 to 8: Qualify automatically for the Round of 16 as seeded teams.
- Positions 9 to 24: Enter a two-legged knockout playoff round. Teams finishing 9th to 16th are seeded and play the second leg at home against unseeded teams finishing 17th to 24th.
- Positions 25 to 36: Eliminated entirely from European competition (no drop into the UEFA Europa League).
From Round of 16 to the Grand Final
The Round of 16 features the top 8 teams paired against the winners of the playoff round. From this stage forward, the competition proceeds via the traditional two-legged knockout bracket (quarter-finals and semi-finals).
Ties level on aggregate score after 180 minutes proceed directly to 30 minutes of extra time and penalty kicks. The single-match Grand Final is hosted at a prestigious pre-selected neutral European stadium.

Frequently Asked Questions
Are there still away goals in the knockout phase?
No. UEFA abolished the away goals rule across all European club competitions in 2021. Ties level on aggregate after 180 minutes proceed directly to extra time and penalties.
Can teams from the same country play each other in the league phase?
In the 36-team league phase, teams generally cannot play clubs from their own association, unless a country has five or more teams qualified, where a maximum of one domestic clash is allowed.
