The 2025-26 UEFA Champions League has produced one of the most dramatic knockout rounds in recent memory. Real Madrid eliminated. Barcelona eliminated. Liverpool dispatched in three matches by PSG without scoring a single goal. And at the centre of it all, an Arsenal side that has gone eight matches unbeaten in this competition, dropping zero points from the group stage and marching into the semi-finals with a composure that no previous version of this club has managed at this level.
Two semi-final ties now stand between the four remaining clubs and the final at Munich's Allianz Arena on 30 May 2026. Arsenal host Atlético Madrid at the Emirates on Tuesday 5 May. Bayern Munich host Paris Saint-Germain at the Allianz Arena on Wednesday 6 May. Both second legs follow the week after.
Here is everything you need to know: the highlights that shaped the semi-finals, the numbers behind each club, and predictions for how these ties will unfold.
The Road to the Semi-Finals: Key Results That Defined the Tournament
Arsenal: Flawless and Relentless
Arsenal have been the standout team of this Champions League campaign. Their record across eight matches reads: eight wins, zero draws, zero losses, 24 points - a perfect group stage by any measure.
The quarter-final against Atlético Madrid is now at the semi-final stage, with the first leg ending 1-1 in Madrid on 29 April. Arsenal's away goal at the Metropolitano came via a composed finish that silenced one of European football's most hostile atmospheres. Atlético pulled level before the end, setting up an Emirates second leg in which Arsenal carry the slight advantage of home ground and a 58.3% win probability.
Before that, Arsenal dispatched Sporting CP across two legs: a 1-0 win in Lisbon on 7 April and a goalless draw at the Emirates on 15 April - enough to advance. It was the kind of disciplined, defensively sound progression that Mikel Arteta's side has made their signature in this competition.
Bayern Munich: The Team That Eliminated Real Madrid
The most dramatic result of the quarter-finals belonged to Bayern Munich. Real Madrid, the tournament's most decorated club and holders of the last four Champions League trophies across six years, were eliminated in a tie of extraordinary goals.
Real Madrid won the first leg at the Bernabéu 2-1 on 7 April. Bayern then produced one of the performances of the tournament, winning 4-3 at the Allianz Arena on 15 April to advance 5-4 on aggregate. In a match that swung repeatedly and featured seven goals across 90 minutes, Bayern's clinical finishing and high defensive line eventually proved decisive. The Allianz Arena at full voice in a must-win European night delivered exactly the kind of spectacle the Champions League exists to produce.
Bayern now sit second in the overall standings on 21 points from eight matches: seven wins, one loss.
PSG: Dominant, Clinical, and Three Goals Better Than Liverpool Across 180 Minutes
Paris Saint-Germain's quarter-final against Liverpool produced one of the starkest results of the round. PSG won 2-0 in Paris on 8 April. PSG won 2-0 at Anfield on 14 April. Four goals, none conceded, across two matches against one of England's most feared European sides.
What makes PSG's performance even more striking is the manner of the victories. Liverpool were not simply outscored. They were outplayed, their high press neutralised, their attacking transitions cut off, and their set-piece threat contained. PSG's defensive structure under Luis Enrique has become as impressive as their attacking efficiency.
PSG enter the semi-final against Bayern on 23 points from their overall campaign: four wins, two losses, two draws - a record that places them 11th in the overall standings. But knockout football operates on different logic. The team that won 2-0 twice against Liverpool is a different proposition to the one that stumbled in the group stage.
Atlético Madrid: From Barcelona Elimination to Semi-Final
Atlético Madrid's quarter-final against Barcelona produced one of the ties of the tournament. Atlético won 2-0 at the Camp Nou on 8 April. Barcelona won 2-1 at the Metropolitano on 14 April. Atlético advanced 3-2 on aggregate, eliminating Barcelona in a tie defined by tactical chess, key moments from Ademola Lookman on the Atlético side, and a Barcelona implosion in the first leg that they never fully recovered from.
Atlético's overall record stands at four wins, three losses, one draw for 13 points - lower than their semi-final appearance might suggest, reflecting an inconsistent group stage followed by exceptional knockout form. This is an Atlético side that peaks when elimination is on the table.
Semi-Final Preview 1: Arsenal vs Atlético Madrid
First leg result: Atlético 1-1 Arsenal (29 April, Madrid) Second leg: Arsenal vs Atlético, Tuesday 5 May, Emirates Stadium, 8 PM WAT Win probability (second leg): Arsenal 58.3% | Draw 23.8% | Atlético 17.9%
Arsenal hold the narrow advantage. The away goal at the Metropolitano means Atlético must score at the Emirates if they are to advance. A 0-0 draw sends Arsenal through. Any Arsenal goal means Atlético need at least two.
The Emirates in a Champions League semi-final is a fixture that this generation of Arsenal supporters has not experienced before. The atmosphere will be extraordinary. The question is whether the occasion lifts the team or tightens them.
What Arsenal need to do: Control possession, press high, and use the width. Atlético's defensive block is compact and difficult to break down centrally. Arsenal's best route to goal runs through the flanks and into the channels behind Atlético's aggressive pressing line.
What Atlético need to do: Score first. If Arsenal concede early at the Emirates, the match becomes significantly more open and Atlético's counter-attacking transitions, the most dangerous weapon in Diego Simeone's tactical arsenal, become exponentially more threatening.
Key player to watch (Arsenal): Martin Ødegaard. The Norwegian midfielder controls the tempo of every Arsenal move and his ability to find pockets of space in tight defensive systems is what separates Arsenal's build-up from simply recycling possession.
Key player to watch (Atlético): Ademola Lookman. The Nigerian forward has been exceptional since joining in January 2026, scoring key goals in the Barcelona tie including a strike at the Camp Nou that effectively ended the first leg as a contest. A player in this form, against former club territory, in a semi-final, is exactly the kind of variable that changes matches.
Prediction: Arsenal 2-0 Atlético Madrid (Arsenal advance 3-1 on aggregate). The Emirates crowd, the pressure on Atlético to attack, and Arsenal's superior recent form collectively favour the home side. If Atlético score first, all bets are off. But Arsenal's defensive record in this tournament is exceptional, and Arteta will set up to exploit the space Atlético must leave when chasing the game.
Semi-Final Preview 2: Bayern Munich vs PSG
First leg result: PSG 5-4 Bayern Munich (28 April, Paris) Second leg: Bayern Munich vs PSG, Wednesday 6 May, Allianz Arena, 8 PM WAT Win probability (second leg): Bayern 57.3% | Draw 19.2% | PSG 23.5%
This tie has already produced nine goals in the first leg. PSG won 5-4 in a match at the Parc des Princes that was as chaotic as the scoreline suggests. Bayern now need to win by two or more goals at the Allianz Arena to advance. Win by one and the tie goes to extra time. Win by exactly two and it goes to extra time and potentially penalties.
PSG only need a 1-1 draw at the Allianz Arena to reach the final. That defensive posture suits Luis Enrique's team enormously, given how well they contained Liverpool in the quarter-final.
What Bayern need to do: Replicate their 4-3 home performance against Real Madrid. The Allianz Arena in must-win mode, with the support fully behind the team, is an environment Bayern have exploited repeatedly this season. They need a fast start, ideally a goal within the first 20 minutes, to shift the tie's psychological balance.
What PSG need to do: Score on the counter. The pattern of this tie, and of PSG's European campaign generally, involves absorbing pressure and striking on the transition. If Bayern chase the game and leave space in behind, PSG are exactly the team to punish it. One away goal changes everything.
Key player to watch (Bayern): Harry Kane. The England captain has been one of the most consistent centre-forwards in Europe this season. In a match where Bayern need goals, Kane's combination of clinical finishing, hold-up play, and movement in the box is what their attacking system revolves around.
Key player to watch (PSG): Ousmane Dembélé. The French winger's direct running, pace in transition, and ability to create chances from nothing are perfectly suited to PSG's counter-attacking brief in this second leg. If the Allianz Arena opens up as Bayern push for goals, Dembélé will be the most dangerous player on the pitch.
Prediction: Bayern Munich 3-1 PSG (tie level at 7-7 on aggregate, goes to extra time and penalties). This is the more genuinely unpredictable of the two ties. A Bayern win on the night feels likely given home advantage and the Allianz Arena atmosphere in an elimination match. But PSG's ability to score on the counter makes a clean sheet an unrealistic expectation. The scenario that feels most probable: a high-scoring Bayern win that takes the tie to extra time, with penalties as the ultimate decider.
Penalty shootout call: Bayern Munich advance. Their experience in knockout football, their home support, and Kane's ice-cold record from the spot collectively tip the balance.
The Overall Picture: Who Lifts the Trophy in Munich?
If the predictions above hold, the Champions League final on 30 May at the Allianz Arena will feature Arsenal against Bayern Munich - an all-English versus German final in a stadium that Bayern call home.
The irony of Bayern potentially playing a European final at their own ground is not lost on anyone. But finals are determined on the night, not by geography.
Arsenal's case for the trophy: They are the only team in this tournament with a perfect record from the group stage. They have won eight matches and lost none. Their defensive structure is elite, their pressing is organised, and Arteta has built a squad with genuine depth at every position. A team that has not dropped a point in eight European matches has earned the right to be called favourites.
Bayern's case for the trophy: They have eliminated the tournament's most decorated club. Their home support in a final at the Allianz Arena would be overwhelming. And a team that scored four against Real Madrid and could score three or more against PSG in the second leg is a team in extraordinary attacking form at exactly the right moment of the season.
The wildcard: If PSG produce an upset at the Allianz Arena and advance, the final becomes a genuinely different conversation. PSG have shown they can eliminate elite opponents. A PSG vs Arsenal final would pit the most free-scoring team in the knockout rounds against the most defensively solid.
Champions League Standings: Full Picture
For context, here is where the four remaining clubs sit in the overall tournament standings after the group stage:
| Rank | Club | W | D | L | Points |
|---|---|---|---|---|---|
| 1st | Arsenal | 8 | 0 | 0 | 24 |
| 2nd | Bayern Munich | 7 | 0 | 1 | 21 |
| 11th | PSG | 4 | 2 | 2 | 14 |
| 14th | Atlético Madrid | 4 | 1 | 3 | 13 |
The standings tell a clear story: Arsenal and Bayern are the competition's two dominant forces by record. PSG and Atlético are knockout specialists who have outperformed their group stage records when elimination was on the table.
Conclusion
The 2025-26 Champions League semi-finals offer two distinct stories. Arsenal vs Atlético is the tie of defensive discipline versus counter-attacking threat, with a slight but meaningful advantage to the home side. Bayern vs PSG is nine goals in the first leg and the promise of more to come, a tactical battle that could end anywhere from a routine Bayern win to a PSG upset for the ages.
What is not in doubt is the quality. These are four of the most compelling clubs in European football, each with the capacity to win a Champions League trophy. Two of them will be eliminated next week.
The final in Munich on 30 May cannot come soon enough.
