Marseille grabbed their opener on the break. It was a nicely crafted move, with ex-Manchester United man Mason Greenwood feeding USMNT winger Weah, who lashed home from close range past Thibaut Courtois.
But the visitors were leaky at the back, and never seemed equipped to hold onto their lead. Madrid responded swiftly after veteran French midfielder Geoffrey Kondogbia tripped Rodrygo - handed an unlikely start over Vinicius Jr - in the box. Mbappe stepped up to slam home the penalty.
Madrid had plenty of chances as the game wore on. Their goal-scorer stung the palms of the goalkeeper on a couple of occasions, and Arda Guler created problems. But Marseille, too, were dangerous on the break, as Weah forced Courtois into action here and there.
A hugely rash moment from Carvajal with less than 20 minutes to go seemed to hand the visitors the advantage. The veteran defender headbutted Geronimo Rulli after a heated exchange, and was given his marching orders once the referee had been sent to the monitor following a lengthy VAR check.
But Los Blancos, in typical Champions League fashion, found a way. They needed a stroke of luck, with Facundo Medina inadvertently handling the ball while making a tackle in the box. The referee rather harshly handed Madrid their second penalty of the night and Mbappe, inevitably, converted to snatch the three points.
