Brentford are hoping to make it three Premier League wins out of three at Stamford Bridge – no team has ever won each of their first three matches away to Chelsea in the competition.
The Bees are unbeaten in the past three meetings, scoring a total of six goals and conceding just one.
Chelsea’s injury status is improving, though Reece James is not quite fit enough to start yet and Armando Broja is set to miss out once again.
