Oct 15 (Reuters) - Chelsea demolished the team that succeeded them as Premier League winners when champions Leicester City succumbed tamely 3-0 at Stamford Bridge on Saturday.
Goals from the Premier League's leading marksman Diego Costa, Eden Hazard and Victor Moses ensured Leicester boss Claudio Ranieri's visit to his old club was a far cry from five months ago when the Foxes received a guard of honour for their title triumph.
The unmarked Costa's seventh-minute strike was his seventh goal of the season, before Chelsea's dominance was further rewarded, following more comedy defending, by Hazard's expertly-taken second.
Moses finished a brilliant one-two 10 minutes from time to leave Leicester as the first English top-flight champions since Blackburn Rovers 21 years ago to lose their opening four away games of the season. (Reporting by Ian Chadband, editing by Ed Osmond)
