PSG has now won the season-opening trophy on fourteen separate occasions.
Paris Saint-Germain needed a stoppage-time leveler followed by a successful spot-kick decider to overcome Marseille in the Gulf and capture a fourth straight Trophee des Champions victory.
The Champions League holders seemed to be coasting towards a straightforward win in the showdown between the French league champions and the French Cup holders after the French winger found the net in the opening stages.
Yet, Marseille fired two times in the closing moments to take a surprise advantage. First, the English forward converted from the spot-kick, before the defender unfortunately turned the ball into his own net for an own goal.
In a breathtaking twist of fortune, Goncalo Ramos snatched a crucial leveler in the dying moments to force the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving crucial attempts from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all converted successfully for Paris Saint-Germain to seal a 4-1 penalty win.
Now 14-time winners PSG, who met last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now won this trophy for the 12th time in the past thirteen years.
