Scorers : Eden Hazard 47',Collins 77',Diego Costa 89'
A late strike from Diego Costa after Collins had cancelled out an ever present Eden Hazard's penalty in Antonio Conte's first competitive game as Chelsea manager.
The Italian named an unchanged XI from the game against Werder Bremen last weekend,with Cesc Fabregas the only notable exclusion.Kante made his Chelsea league debut alongside Matic and Oscar in a three man midfield.
As would be expected from a London derby,it was a fierce first half that saw three yellow cards,first to debutant N'golo Kante then to Costa and Collins after a tussle.
