Chelsea condemned defending Premier League champions Leicester to a fourth consecutive away defeat with a dominant display at Stamford Bridge. The Blues were ahead inside seven minutes when Nemanja Matic flicked on Eden Hazard's corner for Diego Costa to smash home. A David Luiz free-kick struck the post, before Pedro played in Hazard, who rounded Kasper Schmeichel to slot in. Luiz hit his own post when clearing a cross, but Victor Moses' finish after a one-two with substitute Nathaniel Chalobah completed the scoring.
