PSG has now claimed the season-opening trophy on fourteen different occasions.
Paris Saint-Germain needed a dramatic leveler followed by a perfect penalty shootout to overcome Marseille in Kuwait and secure a fourth straight Trophee des Champions victory.
The Champions League holders appeared to be sailing towards a comfortable win in the match featuring the Ligue 1 winners and the Coupe de France holders after the French winger found the net in the opening stages.
Yet, the southern French side struck twice late to seize a surprise lead. Initially, the English forward converted from the spot-kick, before the defender inadvertently directed the ball into his own net for an own-goal.
In a remarkable turn of fortune, Goncalo Ramos snatched a crucial leveler in the final seconds to send the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, saving decisive attempts from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and the young talent all scored successfully for PSG to complete a 4-1 penalty win.
The record winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now lifted this trophy for the 12th time in the last 13 years.
