The former Manchester United man grabbed the winning goal of a hard-fought encounter at Stade Velodrome as the champion extended its unbeaten Ligue 1 run to 34 games.
Angel Di Maria's second-half strike handed Paris Saint-Germain a ninth successive Classique victory as Marseille was beaten 2-1 in Ligue 1.
Di Maria scored his ninth league goal of the campaign with 19 minutes remaining of the clash at Stade Velodrome to break home fans' hearts, after their side had dominated for most of a lively and free-flowing contest.
Marseille had not beaten its guest from the capital in any of the last 10 meetings between the teams and another disappointing night seemed inevitable when Zlatan Ibrahimovic gave the visiting side an early lead with his 21st league goal of the campaign.
