PSG has now secured the season-opening trophy on fourteen separate occasions.
Paris Saint-Germain required a stoppage-time equaliser followed by a successful penalty shootout to overcome Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders seemed to be coasting towards a straightforward win in the match between the Ligue 1 winners and the French Cup winners after Ousmane Dembele opened the scoring in the opening stages.
Yet, the southern French side fired twice late to seize a shock 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 breathtaking turn of events, Goncalo Ramos grabbed a vital leveler in the dying seconds to send the match into a penalty shootout. PSG goalkeeper Chevalier then emerged as the hero, saving decisive attempts from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored with composure for PSG to complete a 4-1 shootout win.
The record champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now lifted this competition for the 12th time in the last 13 years.
