PSG has now won the season-opening trophy on fourteen separate times.
Paris Saint-Germain required a stoppage-time equaliser followed by a perfect spot-kick decider to get past their arch-rivals in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be sailing towards a straightforward triumph in the showdown between the Ligue 1 winners and the Coupe de France winners after the French winger found the net in the opening stages.
However, the southern French side struck twice late to take a shock advantage. Initially, the English forward converted from the spot-kick, before the defender inadvertently turned the ball into his own net for an own-goal.
In a breathtaking twist of events, Goncalo Ramos snatched a vital equaliser in the final seconds to send the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, stopping crucial kicks from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to complete a 4-1 shootout victory.
Now 14-time champions PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now lifted this trophy for the twelfth time in the past 13 years.
