Paris Saint-Germain 4, Barcelona 1

Kylian Mbappé scored twice as Paris Saint-Germain reversed its first-leg loss at home to return to the Champions League semifinals with a win over Barcelona on Tuesday.

PSG took advantage of a first-half red card to Barcelona defender Ronaldo Araujo to advance 6-4 on aggregate and keep its title hopes alive in Mbappé's last season in Paris.

Former Barcelona forward Ousmane Dembélé and Vitinha also scored for PSG after Araujo was sent off in the 29th minute for fouling Bradley Barcola to stop a breakaway.

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

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

Mbappé scored his goals in the 61st and 89th minutes. The France star is hoping to win what would be a first Champions League title for himself and for PSG before he leaves the club.

Barcelona opened the scoring in its first attack with a fortuitous goal by Raphinha after Lamine Yamal’s low cross from the right side bounced off the shin of the Brazil forward and went into the net.

PSG equalized about 10 minutes after Araujo was sent off, with Dembélé finding the net by the far post after a cross by Barcola. Dembélé was loudly jeered by the Barcelona crowd when he was substituted in the final minutes.

PSG took the lead when Vitinha fired a low shot from outside the area in the 54th. The visitors increased their lead when Mbappé converted a penalty kick after Dembélé was brought down by João Cancelo inside the area.

Barcelona had chances to get back into the game, with Ilkay Gündogan hitting the post in the 56th and both Robert Lewandowski and Raphinha squandering chances toward the end of the match.

Mbappé's second goal came from close range in a breakaway in the final minutes.

Barcelona coach Xavi Hernández was sent off for complaining in the 56th.

Borussia Dortmund 4, Atlético Madrid 2

Marcel Sabitzer scored late and set up two goals to send Borussia Dortmund into the Champions League semifinals with a helter-skelter win over Atlético Madrid.

After losing the first leg of their quarterfinal 2-1 in Madrid, 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.

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

Then Sabitzer set up Niclas Füllkrug in the 71st minute for the Germany forward's first goal after nine scoreless games, and Sabitzer scored himself three minutes later to send Dortmund into the last four.

It stretched Dortmund's unbeaten run at home in the Champions League to 10 games.

Atlético needed goalkeeper Jan Oblak at his best. He denied Brandt, then Karim Adeyemi, before Brandt finally made the breakthrough in the 34th, firing a powerful shot in off Oblak's leg from a difficult angle after eluding former teammate Axel Witsel.

Sabitzer then combined with Maatsen, who surged past two defenders and fired the ball inside the far post in the 39th. It was the Dutch defender's first Champions League goal.

But Atlético only needed four minutes after the break to level the tie when Hummels' attempted clearance of Mario Hermoso's header ended in his own net.

Correa should have scored shortly afterward when he nudged the ball wide. Simeone — dressed sharply in a black suit — flopped to the ground in frustration.

Correa made no mistake in the 64th when he fired in a rebound after his first attempt was blocked.

It put the visitors back in front, but Sabitzer was involved in both goals as Dortmund struck twice in three minutes to send the home fans wild.

Oblak prevented worse for Atlético, which became one of two Spanish teams knocked out Tuesday after Barcelona's 4-1 loss at home to Paris Saint-Germain.

Dortmund next plays PSG in the semifinals.
