Who's Going to Budapest? Everything You Need to Know About the 2026 UCL Semi-Finals

Let's be honest — if you didn't watch the first legs of the 2026 UEFA Champions League semi-finals, you missed two of the most gripping nights European football has served up in years. One game had nine goals. The other had penalty drama, a controversial VAR call, and enough tension to make your palms sweat. And the second legs? They're happening right now.

Here's everything you need to know about the road to Budapest.

The Semi-Final Matchups

Before we dive into the drama, here's the big picture. Four teams remain in the race for European glory:

PSG vs Bayern Munich — First leg: PSG won 5-4 (Paris). Second leg: Allianz Arena, Munich — Wednesday, May 6

Arsenal vs Atlético Madrid — First leg: 1-1 draw (Madrid). Second leg: Emirates Stadium, London — Tuesday, May 5

The final takes place on Saturday, May 30 at the iconic Puskás Aréna in Budapest, Hungary. Neither Arsenal nor Atlético have ever been crowned champions of Europe, while PSG are the defending title holders. The stakes could not be higher.

PSG 5-4 Bayern Munich: A Night That Will Live Forever

Where do you even start with this one?

If you were looking for a reason to fall in love with football all over again, PSG vs Bayern Munich on April 28 was it. Nine goals. Three lead changes. A comeback that nearly happened and very nearly didn't. It was, quite simply, one of the greatest Champions League matches ever played.

Bayern drew first blood when Harry Kane stepped up to convert a penalty in the 17th minute — his 54th goal of the season and the sixth consecutive Champions League match in which he'd found the net, making him the first English player to achieve that feat. For a moment, it seemed like the Germans were in control.

PSG had other ideas.Khvicha Kvaratskhelia — the Georgian wizard who has been absolutely electric since joining the French champions — curled in a leveller that the Parc des Princes absolutely erupted for. João Neves then nodded PSG ahead before Michael Olise brought Bayern level in first-half stoppage time. When Ousmane Dembélé converted a penalty to make it 3-2 right before the break, the crowd couldn't believe what they were watching. Nor could anyone else.

The second half was even more outrageous. Kvaratskhelia grabbed his second, then Dembélé tucked in a near-post strike to put PSG 5-2 up before the hour mark. It looked done and dusted. But Bayern, being Bayern, refused to lie down. Dayot Upamecano headed in from a free-kick, and just minutes later Luis Díaz — who had a goal controversially ruled out before VAR overturned the decision — brilliantly brought down Kane's lobbed pass and bent a stunning effort into the far corner. 5-4.

That was the end of the scoring, but absolutely nobody was bored. By the final whistle, the stats told their own story. It was the first European semi-final in history where both teams had scored four or more goals. It matched the highest-scoring semi-final in European Cup history. Manuel Neuer, Bayern's legendary goalkeeper, failed to make a single save all night. PSG's 100th win in the Champions League proper. The records kept coming.

Dembélé, named Man of the Match, summed it up perfectly afterwards: "It was a match between two great teams who attack, who don't hesitate... We're going to attack, and they're going to attack too."

The second leg at the Allianz Arena is on Wednesday. Only five more goals are needed to set a new record for the highest-scoring Champions League knockout tie in history. Don't rule it out.

Arsenal vs Atlético Madrid: Every Inch Matters

If the PSG-Bayern game was a fireworks display, then Arsenal vs Atlético Madrid was a chess match with a hand grenade hidden under the board.

The first leg at the Riyadh Air Metropolitano on April 29 finished 1-1, and the result was heavily shaped by decisions in the penalty area. Viktor Gyökeres — Arsenal's Swedish hitman who has been in sensational form — won and converted a spot kick to put the Gunners ahead just before half-time, becoming the first Swedish player to score in a Champions League semi-final since the competition was rebranded in 1992. Julián Álvarez then answered with a perfectly placed penalty of his own ten minutes into the second half.

There was controversy too. Late in the game, Eberechi Eze appeared to be clipped inside the box by David Hancko, but the penalty was overturned after a VAR review — a decision Arsenal were visibly furious about.

Still, a 1-1 away draw gives Arsenal the slight edge going into tonight's second leg at the Emirates. They're at home. They're unbeaten in this entire Champions League campaign — ten wins and three draws from thirteen matches, a record no other team can match this season. They've also beaten Atlético 4-0 earlier in this very competition.

But Diego Simeone doesn't do straightforward. The Argentine has taken Atlético to Champions League finals before (2014 and 2016, both times beaten by Real Madrid), and his ability to grind out results in knockout football is the stuff of legend. Álvarez, despite going off slightly injured in the first leg, is expected to start and he's been one of the best players in this tournament — averaging a goal or assist every 80 minutes.

Mikel Arteta, speaking ahead of the second leg, made clear his side know the size of the moment: "We are in an incredible position — the semifinal of the Champions League. We have to play in front of our people. It's in our hands."

In our hands, indeed. If Arsenal win tonight, they reach their first Champions League final since 2006. If Atlético hold firm and pull off the upset, Simeone inches closer to the one trophy that has always eluded him.

Key Players to Watch

Khvicha Kvaratskhelia (PSG) — Two goals in the first leg and he's been unstoppable in the knockout stages. Only Harry Kane has more Champions League goal involvements since Kvara joined PSG.

Harry Kane (Bayern Munich) — 54 goals this season and counting. He nearly dragged Bayern back from 5-2 down almost single-handedly. Don't write him off in Munich.

Viktor Gyökeres (Arsenal) — The Swede is having the season of his life. A goal in both legs of this semi-final would put him in truly elite company.

Julián Álvarez (Atlético Madrid)— Linked with a move away from Madrid this summer, Álvarez has every reason to make tonight's game the performance of his career. He leads the entire Champions League for high intensity pressures this season and has been everywhere for Atlético.

Who Has the Edge?

Honestly? Both ties are beautifully poised.

PSG hold a one-goal advantage but gave away two late goals at home — at the Allianz Arena, a rampant Bayern side will fancy themselves to turn it around. Yet PSG have the quality, the confidence, and the history of winning the big moments this season.

Arsenal are slight favourites for their tie. Home advantage matters. Being unbeaten all season matters. But Simeone's record in knockout football is hard to ignore, and Atlético's perfect record in European semi-finals against English clubs adds an extra layer of intrigue.

 What's at Stake: The Road to Budapest

The final at the Puskás Aréna in Budapest on May 30 will see two of football's great clubs going for the ultimate prize — and potentially making history in the process.

For Arsenal, it would be only their second Champions League final appearance. For Atlético, it would be their third final under Simeone — and maybe finally their turn to lift the trophy. For PSG, a successful title defence would place them in elite company. And for Bayern, a first final in six years would cap a remarkable season.

No matter what happens in the second legs, one thing is certain: the 2026 Champions League semi-finals have already given us football moments we'll be talking about for a very long time.
