PSG has now won the prestigious trophy on fourteen different occasions.
Paris Saint-Germain required a stoppage-time leveler followed by a successful penalty shootout to get past their arch-rivals in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be coasting towards a comfortable triumph in the showdown between the Ligue 1 winners and the Coupe de France winners after the French winger opened the net early on.
However, Marseille struck twice in the closing moments to take a shock lead. First, Mason Greenwood converted from the spot-kick, before the defender inadvertently turned the ball into his own net for an own-goal.
In a remarkable twist of events, the Portuguese striker snatched a vital leveler in the final moments to force the match into a deciding shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, stopping crucial attempts from Matt O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and the young talent all converted successfully for PSG to seal a 4-1 penalty victory.
Now 14-time winners PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now won this trophy for the 12th time in the past thirteen years.
