PSG took advantage of a first-half red card to Barcelona defender Ronaldo Araujo to advance 6-4 on aggregate on Wednesday (AEST) and make their first last-four appearance since 2021.

Former Barca forward Ousmane Dembele and Vitinha also scored for the visitors after Araujo was red carded in the 29th minute for fouling Bradley Barcola.

"When it was 11 against 11 we were well organised. The sending off changes everything. The match changed completely," said Barcelona coach Xavi Hernandez, who was later sent off himself for complaining.

"We would have liked to play PSG 11 against 11. That should not have been a red card."

Barcelona got off to a good start and opened the scoring with a goal by Raphinha in the 12th, but PSG took control with the man advantage and didn't let the hosts back into the game.

Mbappe scored his goals in the 61st and 89th minutes.

The Catalan side made it to the knockout stage of Europe's top club competition after two consecutive eliminations in the group stage.

In Germany, Marcel Sabitzer scored late and set up two more goals to send Borussia Dortmund into the semis with a helter-skelter 4-2 win over Atletico Madrid.

After losing the first leg of their quarter-final 2-1 in the Spanish capital, Dortmund had to come from behind twice over two legs to advance 5-4 on aggregate.

Julian Brandt opened the scoring to level the tie before Sabitzer set up Ian Maatsen to give Dortmund a 2-0 lead on the night.

Atletico coach Diego Simeone responded with three changes at the break and they all paid off. A Mats Hummels own goal and goal from substitute Joaquin Correa put the Spanish side back in front on aggregate.

Then Sabitzer set up Niclas Fuellkrug in the 71st minute for the German forward's first goal in 10 games, and Sabitzer scored himself three minutes later to send Dortmund through.

"That was a rollercoaster, a really great evening," Dortmund chief executive Hans-Joachim Watzke said.

"It's not always like that for Borussia Dortmund. The last time we were in the semi-finals was in 2013. This is a great day for all Borussen."
