Following a shock 1-0 loss to Angers for second-placed AC Monaco on Friday night, the win allowed PSG to move six points clear at the top of the standings on 26 points after 10 games, with Lille third on 18. Lens are seventh on 14 points.
PSG winger Bradley Barcola continued his superb start to the campaign by chasing a long ball down the wing and keeping it in play before flashing it across the goal for Dembele to steer home in the fourth minute.
With the visitors rocked early, PSG should have scored a lot more goals, especially following the dismissal of Khusanov in the 59th minute. However, some poor decision-making and even poorer finishing meant that they failed to add to their tally.
