PSG has now secured the season-opening cup on fourteen different occasions.
Paris Saint-Germain needed a dramatic leveler followed by a perfect penalty shootout to get past their arch-rivals in the Gulf and capture a fourth straight Trophee des Champions title.
The Champions League holders seemed to be sailing towards a straightforward win in the showdown featuring the French league winners and the Coupe de France winners after the French winger found the net early on.
Yet, the southern French side struck two times in the closing moments to seize a surprise lead. Initially, the English forward scored from the spot-kick, 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 final seconds to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping decisive attempts from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all converted with composure for PSG to complete a convincing penalty victory.
The record winners PSG, who met last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now won this trophy for the 12th time in the past thirteen seasons.
