Costa and Hazard were instrumental in securing a third win from Conte’s first four home games

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.

Leicester, who left Riyad Mahrez on the bench for the first time in 36 league games, failed to register a shot on target as they struggled to cope against Chelsea’s aggressive pressing and quick passing.

Defeat leaves Claudio Ranieri’s side with eight points from their first eight games – the joint second lowest haul by a defending Premier League champion, along with Chelsea’s team of last season.
