The 2024-25 season rebuilt the Champions League from the ground up. The old eight-group structure disappeared, the field grew to 36 teams, and the total number of fixtures jumped from 125 to 189 per season. If you last followed the tournament under the group format, the new system can look unfamiliar, so this guide breaks down exactly how the matches are organized, how clubs advance, and what rules govern play on the pitch.

In shortSince 2024-25, the Champions League uses a single 36-team league phase in which every club plays 8 matches against 8 different opponents. The top 8 advance straight to the Round of 16, teams ranked 9th to 24th meet in a two-legged play-off, and the bottom 12 are eliminated.

What changed in 2024-25

For three decades the competition opened with 32 clubs split into eight groups of four. Each side played six group matches, and the top two from every group moved on. That model was retired after the 2023-24 season. UEFA replaced it with what it calls the league phase, a format borrowed from Swiss-system tournaments used in chess, where every entrant sits in one shared table instead of separate pools.

The headline numbers tell the story. Four extra clubs joined the competition, lifting the field to 36. Every team now plays two more games in the opening stage, eight instead of six. Because all 36 clubs share one standing, results ripple across the whole table rather than staying confined to a single group of four.

How the league phase works

All 36 clubs are seeded into four pots of nine, based on UEFA’s club coefficient ranking. The automated draw then gives each team eight opponents, two drawn from each pot. A club faces four of those opponents at home and four away, but it never plays the same team twice and cannot be drawn against a side from its own domestic league. No team meets more than two clubs from any single country.

Good to knowThe eight-opponent draw is too complex to run by hand, so UEFA uses purpose-built software. An operator pulls each team from a digital pot, and the program instantly assigns a valid set of home and away fixtures that satisfies every seeding and country rule.

Standings follow the familiar scoring system: three points for a win, one for a draw, none for a loss. When clubs finish level on points, the order is settled by goal difference, then goals scored, then away goals scored, then wins, and a series of further tiebreakers after that. Goals scored away no longer carry double weight in knockout ties, but they still serve as one of these league-phase separators.

The single league table replaced eight separate groups, turning the opening rounds into one connected race rather than 32 isolated mini-leagues.

The eight rounds run across the autumn and winter. Powerhouse clubs such as Real Madrid, Manchester City, Bayern Munich, Liverpool and Paris Saint-Germain can no longer coast through a soft group, because a single shared table means a midweek slip costs ground against the entire field.

From 32 to 36: why UEFA changed the format

European club football has reshaped its top tournament several times. The competition began in 1955 as the European Cup, a straight knockout for national champions. It was rebranded as the Champions League in 1992 and added a group stage that grew into the eight-group, 32-team format most fans grew up with. That structure held from 2003-04 until 2023-24.

Pressure for change came from two directions. Big clubs wanted more guaranteed high-profile fixtures and more revenue, a demand that briefly surfaced as the breakaway European Super League proposal in 2021. UEFA responded by expanding its own competition instead. The league phase keeps clubs inside the existing structure while delivering the extra marquee games and the larger broadcast pool the sport’s biggest names were seeking.

Four new entries were added to fill the 36-team field. Two go to the associations whose clubs performed best across all UEFA competitions the previous season, one goes to a domestic league’s next-best side, and one expands the route reserved for national champions. The goal was to reward strong leagues and keep a path open for smaller nations at the same time.

From league table to the final: the knockout path

Where a club finishes in the 36-team table decides its route. The eight highest-ranked sides skip straight to the Round of 16. Clubs that finish between 9th and 24th drop into a knockout phase play-off, a two-legged tie that produces the other eight Round of 16 qualifiers. The 12 teams ranked 25th and below are out, with no parachute into the Europa League, a change from the old format.

Finishing first now carries real weight: only the top eight teams skip the February play-off and walk straight into the Round of 16.

From the Round of 16 onward the tournament looks traditional. Ties are played over two legs, home and away, through the quarter-finals and semi-finals. Seeding earned in the league phase still matters here, because higher-ranked clubs are positioned to host the decisive second leg. The final is a single match at a neutral stadium chosen by UEFA years in advance.

Why this mattersIn the old format a third-place group finish meant a soft landing in the Europa League. Under the new rules, finishing 25th or lower ends a club’s European campaign immediately, so every league-phase result has higher stakes.

Match rules on the pitch

Inside the 90 minutes, the Champions League follows the standard Laws of the Game. League-phase matches that finish level simply stay drawn, with both sides taking a point. Knockout ties are different: if the two legs end level on aggregate, the tie goes to 30 minutes of extra time and, if still tied, a penalty shootout.

One long-standing rule is gone. The away goals rule, which used to break aggregate ties in favor of the team that scored more on the road, was abolished from the 2021-22 season. A level two-legged tie now heads to extra time regardless of where the goals were scored. Teams may also use five substitutions, made within three stoppages, plus an extra change if a match reaches extra time.

The 2025-26 calendar and the 2026 final

The season is spread across nine months. The league phase fills the autumn and early winter, the play-offs and knockout rounds run through late winter and spring, and the showpiece arrives at the end of May. The 2025-26 final is scheduled for 30 May 2026 at the Puskás Aréna in Budapest. The previous edition was won by Paris Saint-Germain, who beat Inter Milan 5-0 in Munich on 31 May 2025.

Money follows the format. UEFA distributes a large pool to participating clubs, with figures of roughly €2.5 billion across the men’s flagship competition in the new cycle reported by UEFA. Extra league-phase games and a bigger field expanded both the broadcast inventory and the prize pot, which is why the overhaul drew interest well beyond the clubs on the pitch.

Frequently asked questions

How many games does each team play in the league phase?

Every club plays eight matches in the league phase, four at home and four away, against eight different opponents. That is two more than the six group games used under the old format. The opponents are drawn from four seeding pots, with two coming from each pot, and no team faces the same side twice or meets a club from its own domestic league. The eight games are spread over eight separate rounds running from September into late January, and all 36 clubs share one combined standing rather than sitting in small groups.

How do teams qualify for the knockout rounds?

Qualification depends on a club’s final position in the 36-team table. The eight teams at the top advance directly to the Round of 16. Clubs that finish from 9th to 24th enter a two-legged knockout play-off in February, and the winners of those ties fill the remaining eight Round of 16 places. Everyone ranked 25th or lower is eliminated. Because finishing in the top eight skips an entire knockout round, position in the league phase has become far more valuable than simply finishing in the top two of an old group.

What happened to the old group stage?

The eight-group, 32-team group stage was retired after the 2023-24 season. UEFA replaced it with the single-table league phase starting in 2024-25, expanding the field to 36 clubs and the total schedule to 189 matches. The change was driven partly by big clubs wanting more high-profile fixtures and revenue, a demand that surfaced during the 2021 European Super League proposal. Instead of allowing a breakaway, UEFA enlarged its own competition. The new structure keeps clubs inside the existing pyramid while adding more marquee games and a larger broadcast pool.

Is the away goals rule still used?

No. UEFA abolished the away goals rule from the 2021-22 season. Previously, if a two-legged tie finished level on aggregate, the team that had scored more goals on its opponent’s ground advanced. That tiebreaker no longer applies in the knockout rounds. A level aggregate now goes to 30 minutes of extra time, and if the score is still tied, a penalty shootout decides the tie. Away goals do still appear as one of several separators when clubs are level on points within the league-phase standings, but they no longer settle knockout ties.

How is the league-phase draw made?

The draw is run with specialized software because the number of constraints makes a manual draw impractical. The 36 clubs are placed in four pots of nine according to their UEFA coefficient. An operator draws each team, and the program automatically assigns eight opponents, two from each pot, while balancing home and away fixtures. The system also enforces the rules that no club can meet a team from its own league and no club can face more than two sides from any single country. The result is a fixture list that would take far longer to build by hand.

When and where is the 2026 final?

The 2025-26 Champions League final is scheduled for 30 May 2026 at the Puskás Aréna in Budapest, Hungary. UEFA selects host stadiums years in advance, which is why the venue is confirmed long before anyone knows the finalists. The final is a single match at a neutral ground rather than a two-legged tie. The previous final, in 2024-25, was held at the Allianz Arena in Munich on 31 May 2025, where Paris Saint-Germain defeated Inter Milan 5-0 to win the club’s first title.

What happens if teams finish level on points?

When clubs end the league phase on equal points, their order is decided by a chain of tiebreakers. The first is overall goal difference, followed by total goals scored, then goals scored away from home, then number of wins, then away wins. If teams remain level after those, further criteria such as disciplinary record and UEFA coefficient come into play. Because the standing is a single 36-team table, these tiebreakers can shift a club several places at once, which may be the difference between a top-eight finish and a spot in the February play-off.

How many teams are eliminated after the league phase?

Twelve clubs are eliminated once the league phase ends, specifically those finishing between 25th and 36th in the table. Unlike the old format, there is no consolation drop into the Europa League for these sides, so their European season is over. Of the 24 clubs that survive, the top eight go straight to the Round of 16, while the 16 teams ranked 9th to 24th must win a two-legged play-off to join them. That leaves 16 clubs in the Round of 16, the same number as under the previous group-stage system.
