Jose Mourinho’s side go into this fixture looking to put distance between themselves and the bottom three, against a Villa side still winless since the opening day.
Chelsea will be without Branislav Ivanovic, who has picked up a hamstring injury which will rule the Serbia international out until November. Thibault Courtois remains a long-term absentee from a Blues’ backline which has kept just one clean sheet all season.
The Blues have no other injury concerns as they seek to continue their imperious recent record against Villa at Stamford Bridge; they have scored 24 goals in their last six matches in this fixture, including victories of 8-0 in 2012 and 7-1 in 2010.
Tim Sherwood is under growing pressure at Villa Park, as his side now sit four points adrift of safety after six defeats in their last seven games.
Gabby Agbonlahor and Adama Traore could make returns for Villa at Stamford Bridge, but Ciaran Clark and Jores Okore won’t feature.
Villa’s tally of six defeats is the worst in the Premier League, and they have won just once at Stamford Bridge since 2002; Sherwood needs to find a winning formula quickly if the Midlands club are to avoid being cut adrift.
