Champions League 2025-26: Guide to the Format

Everything you need to know about the 2025-26 UEFA Champions League — the new league phase format, 36 teams, draw analysis, and tournament favourites.

The 2025-26 Champions League is the second season under the reformed format, and the new structure has kept delivering. Surprise results, tactical variety, and genuine jeopardy in almost every league phase match. With the knockout rounds approaching, here’s a full guide to how the competition works and who’s in contention.

How the new format works

The Champions League ditched the traditional group stage ahead of 2024-25, replacing it with a single league phase involving all 36 clubs. The same structure is back for 2025-26.

League phase

All 36 teams sit in one league table. Each team plays eight matches (four home, four away) against eight different opponents, drawn from across the seeding pots to give everyone a mix of tough and winnable fixtures.

Where you finish determines what happens next:

  • Positions 1-8: Straight through to the Round of 16
  • Positions 9-24: Into the knockout playoff round, a two-legged tie to earn one of the remaining eight Round of 16 spots
  • Positions 25-36: Out of all European competition entirely (no drop-down to the Europa League)

The format has largely killed off dead rubbers. Because everyone shares a single table, almost every match in the final weeks of the league phase has something riding on it. That was the idea, and it has worked.

Knockout rounds

From the Round of 16 onwards, it’s the traditional two-legged format through to the semi-finals. The final is a single match at a neutral venue. This year that venue is the Allianz Arena in Munich.

League phase analysis

The top eight: direct qualification

Finishing in the top eight means skipping the playoff round and going straight to the Round of 16. That’s extra rest, extra preparation time, and two fewer competitive matches while your potential opponents are battling for survival. It matters.

The top eight has largely followed the expected pecking order. Premier League clubs have posted strong records, benefiting from deep squads and the financial muscle to absorb injuries without losing much quality.

Real Madrid, despite a bumpy domestic season, have done what Real Madrid always do in this competition: find a way. Their squad has enough big-game experience to navigate the league phase without drama, and there’s a calmness about how they handle European nights that few other clubs can replicate.

Barcelona’s resurgence has been one of the season’s better stories. La Masia graduates blended with targeted signings have produced a team that is fun to watch and competitive in the biggest matches. Their league phase record backs up what the eye test says: this Barcelona side belongs at the top table again.

Bayern Munich are doing what Bayern Munich do. Build steadily through the autumn, peak in the spring. Their record of six European Cups and near-permanent presence in the last eight isn’t an accident. Squad depth, tactical discipline, and enough individual quality to hurt anyone.

Inter Milan have built on their run to the 2023 final and now look like Italy’s best Champions League bet. Tactically sophisticated and difficult to play against, with enough quality in key positions to win tight knockout ties.

The playoff round

Clubs finishing ninth to twenty-fourth face the playoff round, a two-legged tie where the loser goes home. Some of these matchups involve big names who underperformed in the league phase against dangerous opponents who exceeded expectations. With elimination on the line, these ties have produced some of the tournament’s best football so far.

Eliminated clubs

The harshest part of the new format: finishing 25th to 36th means you’re out of Europe entirely. No Europa League safety net. For clubs that geared their entire season around Champions League involvement, early elimination is a significant blow.

Tournament favourites

Real Madrid

Fifteen European Cups. No other club is close. The current squad may not be the most talented in the draw on paper, but Real Madrid carry a psychological edge in this competition that defies easy measurement. They just win.

Vinicius Junior gives them a genuine match-winner for the biggest occasions. His pace, skill, and improving decision-making make him one of the most dangerous forwards in European football when the pressure is highest. Jude Bellingham adds box-to-box dynamism and goals from midfield. Together, they give Real Madrid the individual quality to decide tight knockout ties.

Manchester City

Guardiola’s pursuit of more Champions League success at City remains one of the defining storylines in European football. Domestic Premier League challenges may actually help this year, freeing up mental energy for Europe. And with Erling Haaland, they have someone capable of outscoring almost anyone over two legs.

City’s biggest weapon is Guardiola’s tactical range. He can set up to dominate possession or to play more direct and counter-attack, and he adjusts his approach match by match. Opponents never quite know which City they’ll face. If De Bruyne is fit for the knockout rounds, they’ll be very hard to stop.

Arsenal

Arsenal’s European ambitions have grown in step with their domestic improvement. Defensive solidity, a real threat from set pieces, and disciplined game management under Arteta make them well-suited to the knockout format, where ties can hinge on a single goal.

The balancing act between their Premier League title push and Champions League commitments is the issue. Arteta needs to manage minutes carefully through the spring, and how well he does that will determine how far Arsenal go.

Barcelona

Barcelona’s return to contention is built on youth and tactical clarity. La Masia keeps producing exceptional players, and the coaching staff have found a way to integrate them into a coherent system that gives the team real energy and directness.

The league phase showed Barcelona can go toe-to-toe with anyone. The flip side of relying on young players is inconsistency, and on a bad night they can look ragged. But on a good night, few teams in Europe are more exciting or more dangerous.

Bayern Munich

Six European Cups and a habit of being there or thereabouts every single year. Bayern have used the league phase to lay the groundwork, and if recent history is any guide, they’ll be a different animal from February onwards.

Their squad mixes German organisation with international attacking talent, and the Allianz Arena final adds another layer of motivation. A home final is rare. Bayern will not waste the opportunity.

The road to Munich

The knockout rounds always deliver. Late goals, tactical chess matches, and the raw emotion of teams fighting to stay alive. The road to the Allianz Arena will test every squad’s depth, nerve, and ability to handle pressure.
