PSG has now won the season-opening cup on fourteen separate occasions.
Paris Saint-Germain required a stoppage-time equaliser followed by a perfect penalty shootout to overcome their arch-rivals in Kuwait and capture a record-extending fourth consecutive Trophee des Champions victory.
The European champions appeared to be sailing towards a straightforward triumph in the match featuring the French league champions and the Coupe de France winners after Ousmane Dembele opened the net in the opening stages.
Yet, Marseille struck twice late to take a shock advantage. First, the English forward scored from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a remarkable turn of events, Goncalo Ramos grabbed a vital equaliser in the dying seconds to send the match into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the hero, stopping crucial kicks from O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all converted with composure for Paris Saint-Germain to complete a 4-1 shootout victory.
Now 14-time winners PSG, who met last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now lifted this competition for the 12th time in the past 13 years.
