Lionel Messi scored the winner as Paris St-Germain beat Lyon to maintain their unbeaten start to Ligue 1 and move two points clear at the top of the table.
Messi found the net inside five minutes with a smart first-time finish after combining with Neymar, who made his seventh assist in the league this term.
It was a sixth PSG goal in all competitions this season for Messi.
Sergio Ramos also had the ball in the net late on, but he was offside following a Messi free-kick.
PSG now hold a two-point lead over Marseille, who are also yet to lose a game this season.
