Alaa Bellaarouch thwarted an early penalty attempt, only to face an unexpected twist as Marco Asensio capitalized on his clearance error, setting up Kylian Mbappe for the opening goal—Mbappe's 20th league strike this season.
Returning the favor, Mbappe later assisted Asensio for a second goal in the 49th minute, with Dilane Bakwa narrowing the gap for Strasbourg.
Despite a late push from Strasbourg in the final 20 minutes, Gianluigi Donnarumma stood firm, denying them a second goal.
With this victory, PSG extends their lead to nine points over Nice, having played an additional game. Meanwhile, Strasbourg maintains their 10th position.
