Serhou Guirassy and Borussia Dortmund did what no else has been able to in 2025 — they beat Barcelona. It still wasn't enough for the Bundesliga side to reach the Champions League semifinals, though.

Guirassy scored a hat-trick and still ended up on the losing side, as Dortmund's 3-1 win over Barcelona — the Spanish club's first defeat of any sort since December — wasn't enough to prevent a 5-3 aggregate loss.

After being swept aside 4-0 in the first leg of the quarterfinal, Dortmund had nothing to lose on Tuesday, and attacked Barcelona from the start, leaving the visitors off-balance.

Barcelona coach Hansi Flick, who has plenty of experience of facing — and beating — Dortmund from his time in the German league, said the passionate home crowd meant he'd expected a tough second leg, despite his team's four-goal lead.

"I had a little bit of a feeling that something like this was coming," Flick told broadcaster Amazon Prime. "Today, you have to say congratulations to Dortmund, they played a very good game, and congratulations to my team, they're in the semifinals."

It was an unusually quiet game for Barcelona's prolific forwards Raphinha and Robert Lewandowski, who have 12 and 11 Champions League goals, respectively, so far this season. The closest either came to scoring was a tame shot by Raphinha at Dortmund goalkeeper Gregor Kobel.
