Zlatan Ibrahimovic scored a hat-trick on his return from injury as French champions Paris St-Germain thrashed Ligue 1 rivals St Etienne.
A farcical own goal by away keeper Stephane Ruffier, who failed to control a routine backpass and allowed the ball to roll in, set PSG on their way.
Ibrahimovic doubled the lead just before half-time with a firm header.
He intercepted a backpass for the third, then completed his treble after Edinson Cavani curled in a fourth.
Laurent Blanc’s men have taken eight points from their opening four matches, two adrift of early leaders Bordeaux.
