PSG has now claimed the prestigious trophy on fourteen different times.
Paris Saint-Germain needed a stoppage-time leveler followed by a successful penalty shootout to overcome Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders seemed to be sailing towards a straightforward win in the match between the French league champions and the Coupe de France holders after Ousmane Dembele found the scoring in the opening stages.
Yet, Marseille fired two times late to seize a shock lead. Initially, Mason Greenwood converted from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a breathtaking turn of fortune, Goncalo Ramos grabbed a crucial leveler in the dying seconds to send the contest into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the hero, stopping decisive attempts from O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all converted successfully for PSG to seal a 4-1 shootout victory.
The record winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after completing a domestic double, have now lifted this trophy for the 12th time in the last thirteen seasons.
