PSG has now won the prestigious cup on fourteen separate occasions.
Paris Saint-Germain needed a dramatic leveler followed by a perfect penalty shootout to overcome Marseille in Kuwait and secure a fourth straight Trophee des Champions victory.
The European champions appeared to be coasting towards a straightforward triumph in the match featuring the French league winners and the Coupe de France holders after the French winger found the net in the opening stages.
Yet, Marseille fired two times in the closing moments to seize a surprise advantage. First, the English forward converted from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a remarkable turn of fortune, Goncalo Ramos snatched a crucial leveler in the dying moments to force the contest into a penalty shootout. PSG goalkeeper Chevalier then emerged as the key figure, saving crucial attempts from O'Riley and Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to complete a 4-1 shootout win.
The record champions PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now won this competition for the 12th time in the last thirteen seasons.
