How the Champions League Format Works

The UEFA Champions League is European club football's biggest prize, and since the 2024-25 season it has used a format that confuses even long-time fans: the old eight groups of four are gone, replaced by a single giant league. Here is how the whole competition actually works, from September to the final.

The league phase

Thirty-six clubs enter the main competition. Instead of being split into groups, every club sits in one combined league table. Each club plays eight matches against eight different opponents, four at home and four away. Crucially, they do not play everyone, and no two clubs necessarily face the same eight opponents.

Opponents are assigned by a seeded draw. The 36 clubs are ranked into four pots based on their UEFA coefficient, a rolling measure of European results over recent seasons. Every club draws two opponents from each pot, including its own. That means a top seed still has to face two other top seeds, and an outsider gets at least a couple of winnable fixtures.

Wins are worth three points and draws one, exactly like a domestic league. After all eight rounds, the combined table decides everyone's fate.

Who advances, and how

The table splits into three bands:

• Top 8: advance directly to the round of 16.
• 9th to 24th: enter a two-legged knockout playoff. The clubs ranked 9-16 are seeded and face an unseeded club ranked 17-24, with the seeded side hosting the second leg. The eight winners join the top eight in the round of 16.
• 25th to 36th: eliminated from Europe entirely. Unlike the old format, there is no drop into the Europa League.

Finishing in the top eight matters beyond skipping a round. The bracket from the round of 16 onwards is fixed like a tennis draw, and a higher league-phase ranking gives you a theoretically easier path and second legs at home.

The knockout rounds

From the round of 16 to the semi-finals, ties are two-legged: one match at each club's ground, aggregate score decides. Away goals no longer count double; UEFA abolished that rule in 2021. If the aggregate is level after both legs, the second leg goes to extra time and then penalties if needed.

The final is a single match at a neutral venue chosen years in advance.

How clubs qualify in the first place

Most of the 36 places go to domestic league performance from the previous season. The exact allocation shifts slightly each year, but the strongest leagues by UEFA coefficient, in recent seasons England, Spain, Italy and Germany, send four clubs or more. Two extra places go to the two countries whose clubs performed best in Europe the season before, which is why a fifth-placed Premier League club can sneak in. The reigning Champions League and Europa League winners also get a place if they have not already qualified.

Why the format changed

The old group stage produced too many dead fixtures: by matchday five, half the groups were often decided. The single league keeps almost every club alive deep into January, because the difference between 8th and 9th, or 24th and 25th, can hinge on a single goal in the final round, when all 18 matches kick off simultaneously.

The trade-off is complexity. A club's fate now depends on results across the whole 36-team table, so fans need the full standings, not just a four-team group, to know where things stand.

Quick answers

How many games does a club play to win it? Seventeen at most: eight in the league phase, two-legged playoff (if needed), then two-legged ties through to a one-off final.

Can clubs from the same country meet early? Clubs from the same country cannot be drawn against each other in the league phase, but from the round of 16 onwards anyone can meet anyone.

Does winning it qualify you for next season? Yes. The titleholder is guaranteed a league-phase place even if they finish outside their domestic qualification spots.
