Substitute Ángel Correa scored a dramatic winner with the last kick of the game as Atlético Madrid snatched a 2-1 victory away to Paris Saint-Germain on Wednesday, kickstarting their Uefa Champions League campaign and casting a large cloud over the French club's European hopes.

It looked as if the game at the Parc des Princes would end in a draw after Warren Zaire-Emery's early opener for PSG was quickly cancelled out by Nahuel Molina, in what was the first ever meeting of the clubs.

PSG have been let down by their finishing in the Champions League all season and that was the case again here as they failed to convert a host of chances, but Atletico did not look like winning it until Correa struck in the 93rd minute.

The Spaniards would have been the happier of the two teams with a draw, especially as goalkeeper Jan Oblak had been forced into several second-half saves.

Having lost back-to-back matches against Benfica and Lille, the win puts Atlético back on track to at least make the play-off round of this new-look Champions League, with the league phase now at the halfway stage.

The evening was also notable for the pre-match unfurling by PSG fans at one end of the stadium of an enormous banner in support of Palestinians in Gaza.

"War on the pitch but peace in the world," said the banner, which also featured a Lebanese flag.

That may lead to disciplinary action from Uefa, but that will probably be the least of PSG's worries right now.

They may be comfortably on top of Ligue 1 but in the Champions League last season's semi-finalists have just four points, despite playing three of their four games so far at home.

Having edged Girona 1-0 on the opening matchday and then lost 2-0 away to Arsenal, the French champions have since drawn at home to PSV Eindhoven and now lost to Atlético.

They face a tough assignment next away to Bayern Munich and also still have to play Manchester City, meaning their hopes of finishing in the top 24 places and qualifying at least for the play-off round must be in doubt.

Luis Enrique's side will need to quickly improve in front of goal having now scored just three times in their last six Champions League matches, a run stretching back to last season's semi-final loss against Borussia Dortmund. (AFP)
