PSG has now claimed the season-opening cup on fourteen separate times.
Paris Saint-Germain required a dramatic leveler followed by a perfect penalty shootout to get past Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders seemed to be coasting towards a comfortable win in the match between the Ligue 1 champions and the French Cup winners after the French winger found the net early on.
Yet, Marseille struck twice late to seize a surprise lead. First, the English forward converted from the penalty spot, before the defender inadvertently turned the ball into his own net for an own-goal.
In a remarkable twist of events, Goncalo Ramos snatched a crucial equaliser in the dying moments to force the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, stopping crucial attempts from O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all converted with composure for PSG to complete a convincing shootout victory.
Now 14-time winners PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now won this trophy for the twelfth time in the last 13 seasons.
