PSG has now secured the prestigious cup on fourteen separate occasions.
Paris Saint-Germain needed a dramatic leveler followed by a perfect penalty shootout to get past Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders seemed to be coasting towards a comfortable triumph in the match featuring the Ligue 1 champions and the French Cup winners after Ousmane Dembele opened the scoring early on.
Yet, Marseille struck twice in the closing moments to seize a shock lead. Initially, Mason Greenwood scored from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos grabbed a vital leveler in the dying seconds to send the contest into a penalty shootout. PSG goalkeeper Chevalier then stood as the hero, stopping crucial kicks from O'Riley and Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and the young talent all scored with composure for PSG to complete a 4-1 penalty win.
Now 14-time winners PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now won this competition for the 12th time in the last 13 years.
