Quick-fire goals before the break and a Nikola Vujadinovic strike condemned the Ligue 1 champions to defeat despite a sublime late strike from their young attacker
Laurent Blanc's reign as Paris Saint-Germain boss got off to a disappointing start as his side were beaten 3-1 by Sturm Graz on Tuesday, although there was a true moment to savour from starlet Hervin Ongenda.
Robert Beric and Marco Djuricin struck within two minutes of each other to hand the hosts a 2-0 lead before half-time and Nikola Vujadinovic extended their advantage late on.
Ongenda did restore some pride for the French side with five minutes remaining with a stunning lob, leaving Blanc with a few things to ponder after he fielded a team that contained few first-choice stars.
The former France boss named a starting line-up shorn of the likes Zlatan Ibrahimovic, Marco Verratti and Javier Pastore, though their hosts also experimented with the inclusion of new arrivals Beric and Djuricin.
And the Austrian side were treated to a preview of what they might expect in the coming season, as the pair both got on the scoresheet in quick succession with 25 minutes gone.
Beric opened the scoring after deceiving goalkeeper Nicolas Douchez twice, before Djuricin doubled the lead in the 28th minute with a fine finish.
Darko Milanic's men were forced to wait until the 77th minute to add to their total, but did so when centre-back Vujadinovic poked in from close range.
But Ongenda still had time to add respectability to PSG's defeat with a sublime finish, as he lifted the ball over goalkeeper Christian Gratzei from the edge of the area for a late consolation.
PSG continue their pre-season preparations in Austria with a clash against Rapid Vienna on Friday.
