Champions League format explained: how 2026/27 works

The men's Champions League has 36 teams in one league table. Each plays eight different opponents. After those matches, the top eight go straight to the round of 16, teams finishing ninth to 24th enter knockout playoffs, and teams in 25th to 36th are eliminated. Those are the three cutoffs to watch under UEFA's 2026/27 league-phase rules.

What changed from the old group stage?

The league phase replaced the eight groups of four in 2024/25. Previously, each club faced three group opponents twice. Under the new structure, clubs face a wider selection of opponents and compete for positions in a shared ranking. So “Champions League new format” refers to the change introduced in 2024/25, not a new reform starting in 2026/27. UEFA's format explainer explains that transition.

Which clubs are playing in 2026/27?

Here is a selection of the current league-phase participants from UEFA's 2026/27 team guide, checked on October 3, 2026. This identifies clubs and countries, not their league positions.

Club	Country
Arsenal	England
Paris Saint-Germain	France
Bayern München	Germany
Inter	Italy
Barcelona	Spain
Club Brugge	Belgium
Porto	Portugal

Why only eight games in a 36-team league?

This is not a full round robin: a club does not face all 35 other teams. The draw divides the field into four pots of nine and assigns each club two opponents from every pot, including its own. It plays one opponent from each pot at home and the other away, making four home games and four away games.

The pots help determine the fixture list; they do not become separate groups or tables. Two clubs can finish next to each other without having played each other. Nor should you expect a return fixture against every league-phase opponent. The home-and-away pairing familiar from knockout football comes later. See Article 16.

How does qualification work?

A win earns three points, a draw one and a defeat none. Final position determines the next step:

Final league position	What happens next
1–8	Direct entry to the round of 16
9–24	Knockout playoffs for the remaining eight round-of-16 places
25–36	Eliminated

Reaching the top 24 therefore does not mean reaching the last 16. The playoff winners join the top eight; the playoff losers go out. Clubs eliminated after the league phase do not drop into the Europa League. UEFA's format guide sets out that route.

Real qualification cutoffs from 2024/25

These rows come from UEFA's completed 2024/25 league-phase table, after the final matchday on January 29, 2025. Countries follow UEFA's team guide for that season. They are historical results, not the 2026/27 standings or guaranteed points targets.

Position	Club	Country	Points	Goal difference	Outcome
8	Aston Villa	England	16	+7	Round of 16
9	Atalanta	Italy	15	+14	Knockout playoff
24	Club Brugge	Belgium	11	−4	Knockout playoff
25	GNK Dinamo	Croatia	11	−7	Eliminated

Aston Villa finished above Atalanta on points despite Atalanta's better goal difference. Club Brugge and GNK Dinamo were level on points, so goal difference separated them at the elimination cutoff. Position depends on the whole season's table, not a fixed qualification total.

For teams level on points at the end of the league phase, the first tiebreaker is overall goal difference, followed by goals scored, then away goals scored. UEFA specifies further criteria if they remain tied; head-to-head results are not the first test. See the complete order in Article 18.

What happens in the knockout rounds?

The playoffs, round of 16, quarter-finals and semi-finals normally have two legs, one at each club's ground. The team with more goals across the pair advances. That combined score is aggregate: it covers that tie, not the club's league-phase points or its goals across the whole season. Article 20 defines the system.

In the 2024/25 quarter-finals, Paris Saint-Germain (France) beat Aston Villa (England) 3–1 at home, then lost the return 3–2 on April 15, 2025. Paris still advanced 5–4 on aggregate: 3 + 2 goals against Villa's 1 + 3. UEFA's match report records both the second-leg defeat and the overall victory.

If aggregate scores are level after normal time in the second leg, two 15-minute periods of extra time follow, then a penalty shoot-out if needed. Away goals do not settle a tied knockout contest. Article 21 gives the deciding procedure.

The final is a single match, with extra time and penalties available if required. There is no second leg to recover a deficit. Article 22 covers the final.
