Paris St-Germain 5-0 St Etienne

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.
