Paris Saint-Germain took firm control of their Champions League knockout phase playoff on Tuesday, registering a resounding 3-0 victory in the first leg away at Brest. Forward Ousmane Dembélé was the star of the show, netting a brace to propel his team to this impressive win.

This encounter was a significant one in Champions League history, as it was merely the second occasion where two French teams went head-to-head in the competition. Despite Brest having opportunities of their own throughout the match, Paris Saint-Germain demonstrated their clinical edge, dictating the flow of the game and ultimately securing a dominant result.

PSG broke the deadlock after 21 minutes, with Vitinha converting a penalty after Pierre Lees-Melou's handball.

Brest were very much in the match when Abdallah Sima's header hit the post just after the half-hour mark.

The visitors, however, doubled their lead when Dembele cut inside from the right flank and beat the keeper at his near post with a low strike in the final minute of the first half, scoring in his eighth consecutive match for PSG.

Just after the break, PSG's Désiré Doué was played through and slotted home with ease, but after a minute-long VAR check, the goal was ruled out for offside.

In the 66th minute, Dembele secured his brace, latching onto a loose ball in the box before sending a shot past Brest keeper Marco Bizot.

The 27-year-old Dembele has now scored 18 goals in his last 11 matches, while PSG are unbeaten against Brest in their last 31 encounters, with their last defeat coming in 1985.

The result leaves Brest with a mountain to climb in the return leg at the Parc des Princes on Feb. 19.
