Paris St Germain drew a blank for the first time this season as they surprisingly surrendered their 100 per cent start with a goalless draw at Montpellier.
Unai Emery's side had scored 21 times in their first six Ligue 1 fixtures and also put five past Celtic in the Champions League, but their high-powered attack misfired at the Stade de la Mosson.
That will inevitably draw more attention to the absence of world-record signing Neymar, who was left out of the squad with what was reportedly a minor foot injury.
