Barcelona and Atletico Madrid both recorded wins in the first legs of their Champions League quarter-final on Wednesday night.
The LaLiga champions left France with a narrow 3-2 win over PSG.
Raphinha opened the scoring at the Parc des Princes, but the hosts went in front thanks to goals from Ousmane Dembele and Vitinha.
Barca levelled the game through another Raphinha goal, before Andreas Christensen headed in the winner.
In the other game of the night, Rodrigo De Paul and Samuel Lino gave Atletico a two-goal lead.
Dortmund were only to half the deficit through Sebastien Haller’s smart finish.
The second legs for both ties will be played next Tuesday.
