Lionel Messi won a penalty that Sergio Ramos converted as Paris Saint-Germain got a new era under Christophe Galtier off to a winning start on Friday.
The French champions, who appointed Galtier as Mauricio Pochettino's successor earlier in July, saw off second-tier side Quevilly-Rouen 2-0 in a behind-closed-doors friendly.
Galtier named a starting XI containing a mix of big names and younger players, with Messi partnering Mauro Icardi in attack, while Vitinha, signed from Porto, was given a debut in midfield.
Messi played a big part in PSG's opener as he was brought down in the box for a penalty, which Ramos stepped up to convert midway through the first half.
Without Kylian Mbappe and Neymar for their pre-season opener, PSG were rewarded with a second goal early in the second half through 18-year-old academy player Djeidi Gassama.
PSG, who changed their entire side for the second half, will now fly out to Japan ahead of fixtures with Kawasaki Frontale, Urawa Reds and Gamba Osaka.
