Serhou Guirassy and Borussia Dortmund beat Barcelona in 2025. This was very hard because no one else had done it. But they did not reach the Champions League semifinals.

Guirassy scored three goals, but his team still lost the match. Dortmund won against Barcelona with a score of 3-1. This was Barcelona's first defeat since December. However, Dortmund lost the overall score from the two games, with a final result of 5-3.

Dortmund lost the first game 4-0. So, they had nothing to lose in the second game on Tuesday. They started attacking Barcelona right away, and this surprised Barcelona.

Barcelona coach Hansi Flick said the fans in the stadium were very loud. He thought the second game would be hard, even though his team was winning by four goals.

Flick told Amazon Prime, "I thought this might happen." He also said, "Today, we should say well done to Dortmund because they played well. And well done to my team because they are in the semifinals."

Barcelona's good attackers, Raphinha and Robert Lewandowski, did not score in this game.

Coach Niko Kovac said Guirassy is very important for Dortmund, like life insurance. He played very well in the game and is now famous. He has scored the most goals in the Champions League this season. Kovac said Guirassy needs his teammates to help him, and they did today.

Some people thought Dortmund lost the first game of the quarterfinal. Also, their captain Emre Can and player Carney Chukwuemeka were injured and could not play.

For a time, Guirassy made people believe that something very hard could happen.

Guirassy missed chances in the first game and also missed two more chances at the start of Tuesday's game. But he scored from the penalty spot in the 11th minute after the Barcelona goalkeeper hit Pascal Gross.

Guirassy scored with his head to make it 2-0 in the 49th minute. Then, Ramy Bensebaini accidentally kicked the ball into his own goal. This made it very hard for Dortmund. Fermín López kicked the ball low, and it hit Bensebaini's leg and went into the goal. This was bad for Dortmund because Bensebaini had just helped Guirassy score another goal a short time before.

Guirassy scored his third goal after Ronald Araujo made a mistake. He shot the ball strongly from near the goal in the 76th minute. Now he has scored the most goals in the Champions League this season, with 13 goals.

This gave Dortmund hope to win the game, but Barcelona won in the end.

Barcelona will play against Inter Milan or Bayern Munich in the semifinals. This is the first time they have been in the last four teams of the Champions League since the 2018-19 season. On Tuesday, PSG also got to the semifinals. They won 5-4 against Aston Villa in total, even though they lost the second game 3-2.

Barcelona lost a game. It was their first loss since December 21. They also lost a Champions League game for the first time since September. Their coach, Flick, had won many games. He had only lost seven games out of 50. He had won all seven games against Dortmund before this game.

Dortmund will probably not hear the Champions League song in their stadium for some time.

Last year, the team that came second in the Champions League is now eighth in the German league. There are five games left. They need six more points to get into the top four places to play in the Champions League next year.
