Newcastle have four points from their opening two games, one more than PSG, while Borussia Dortmund and AC Milan picked up their first point in a 0-0 draw in Germany.
The first ever clash between the clubs pitted the sporting interests of Saudi Arabia and Qatar head-to-head.
A Saudi takeover two years ago has transformed Newcastle’s fortunes in similar fashion to how the influx of cash from the Middle East has made PSG the dominant force of French football over the past decade.
PSG boss Luis Enrique warned before the game that Newcastle were the side no one wanted from the fourth pot of seeds and the Premier League side showed why.
Despite being acutely aware of Newcastle’s threat, Luis Enrique boldly stuck with a star-studded front four featuring Kylian Mbappe, Ousmane Dembele, Goncalo Ramos and Randal Kolo Muani.
It could have been very different for the French champions had Dembele’s sweetly-struck volley form Mbappe’s cross found the net rather than flying inches wide early on.
But once the home side, roared on by a raucous 52,000 fans, got their claws into the visitors, they did not let go.
PSG were though architects of their own downfall with the opening goal on 17 minutes.
A slack pass by Marquinhos was intercepted by Bruno Guimaraes to give Alexander Isak a clear sight of goal.
Gianluigi Donnarumma produced a fine save to deny the Swede, but Almiron was on hand to curl into the far corner.
