PSG has now won the season-opening cup on fourteen separate occasions.
Paris Saint-Germain required 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 victory.
The European champions seemed to be coasting towards a straightforward triumph in the showdown featuring the French league winners and the French Cup winners after the French winger found the scoring early on.
Yet, the southern French side fired twice in the closing moments to take a surprise advantage. Initially, Mason Greenwood converted from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a breathtaking twist of fortune, the Portuguese striker grabbed a vital leveler in the final seconds to force the match into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, stopping crucial attempts from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all scored with composure for PSG to seal a 4-1 penalty win.
Now 14-time winners PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now won this trophy for the twelfth time in the past thirteen years.
