One table, not eight groups
From the 2024–25 season the Champions League abandoned the group stage it had used for three decades. Instead of eight groups of four, all 36 clubs now sit in a single league table.
The number of participants rose from 32 to 36. Each club plays eight matches — four at home, four away — against eight different opponents, and never plays the same team twice. Points work exactly as they do in a domestic league: three for a win, one for a draw.
The format is drawn from the Swiss system used in chess tournaments, where players are matched by strength rather than sorted into fixed pools. For the draw, the 36 clubs are divided into four seeding pots by UEFA club coefficient, and each team is drawn against two opponents from each pot, playing one home and one away in each pairing.
The league phase runs from September to January. The knockout rounds begin in February.
What the table decides
When the eight matches are done, the single table splits three ways.
Positions 1 to 8 go straight into the round of 16. They skip February entirely and enter the draw as seeded teams.
Positions 9 to 24 enter a two-legged knockout play-off round in February — eight ties for the remaining eight places in the last 16. Teams finishing 9th to 16th are seeded in that draw; teams finishing 17th to 24th are not.
Positions 25 to 36 are eliminated. This is the change that most altered the competition's stakes: under the previous format, third place in a group meant a drop into the Europa League. Now the bottom twelve are out of European football for the season, with no parachute.
Finishing ninth and finishing twenty-fourth both mean the play-off round, but they are not the same outcome. The seeding advantage runs all the way through the bracket.
Why league position still matters after the league phase
The knockout bracket is shaped by where you finished, and the advantage compounds.
Higher-ranked sides get the second leg at home — in the play-off round for those seeded 9th to 16th, and in the round of 16 for the top eight. The top four in the league phase carry that advantage into the quarter-finals, and the top two into the semi-finals.
The top eight are also paired in the draw so that the sides finishing first and second land on opposite sides of the bracket, meaning the two best league-phase records cannot meet before the final.
One useful wrinkle: if an unseeded club knocks out a seeded one, it inherits that seeding position for the rest of the run. The bracket keeps its shape even when the favourites do not survive it.
Getting in: the qualifying rounds nobody watches
The 36 clubs in the league phase do not all arrive the same way, and most of the field is settled long before September.
Twenty-nine teams qualify in advance: the Champions League and Europa League title holders, the champions of the ten highest-ranked associations, runners-up from the top six, third-placed teams from the top five, fourth-placed teams from the top four, and two places awarded to the associations with the best one-year coefficient.
The remaining seven come through qualifying, which begins in early July — before most domestic seasons have even started. Qualifying is split into two separate streams: a Champions Path for teams that won their national league, and a League Path for those who qualified by finishing second, third or fourth. Five of the seven places go to the Champions Path and two to the League Path.
That split is deliberate. It protects a route into the competition for champions of smaller associations, who would otherwise be drawn against clubs from far stronger leagues at every stage.
What the format changed in practice
Three things are measurably different.
More matches. Guaranteed group-stage football went from six matches to eight. A club reaching the final can now play up to 17 matches in the competition, against a previous maximum of 13.
More variety of opponent. Eight different opponents rather than three played twice means a wider spread of fixtures, and it removes the dead rubber — the final group game between two teams who had already settled their fate.
Harsher elimination. Finishing outside the top 24 ends your European season outright.
The honest caveat: whether the format is better is an argument about taste and calendar congestion, not a question with a factual answer. What is not in dispute is that clubs now need deeper squads. Eight matches against eight different opponents inside ten weeks cannot be navigated with the small core that a four-team group allowed.
