New striker Diego Costa scores as Chelsea beat Burnley 3-1
Diego Costa scored on his Chelsea debut as the title favourites came from behind to outclass newly-promoted Burnley at Turf Moor.
There was the threat of an upset as Burnley's Scott Arfield opened the scoring with a stunner from distance.
But Burnley's lead was short-lived as Costa levelled with a simple tap-in.
Andre Schurrle scored Chelsea's second after a cute Cesc Fabregas pass and Branislav Ivanovic struck from a corner to seal the win for the Blues.
