Frank Lampard still seeks his first non-defeat as interim Chelsea manager after the Blues were comfortably beaten 2-0 by Brentford at Stamford Bridge on Wednesday.
The defeat leaves the Blues on 39 points, meaning that they are just 10 points above the relegation zone and their chances of rallying towards the European spots have perished further.
Cesar Azpilicueta’s own goal came in the 37th minute after a corner was not cleared at the front post, gave Brentford the lead as the ball went past Kepa Arrizabalaga.
Subtitute Brayan Mbuemo came off of the bench to double the Bees’ lead in the 78th minute, with the winger breaking free on the right before cutting inside and firing a fierce strike in at the front post.
Lampard, Chelsea’s all-time record goalscorer, has now lost his opening five games in charge, extending club’s worst run since 1993 in all competitions.
