Callum Hudson-Odoi and Ruben Loftus-Cheek start a second Premier League game in six days.
The pair, both influential in the win over Brighton, retain their places. The only changes from that 3-0 success in our last outing are the return of Toni Rudiger in defence and Gonzalo Higuain up front. Andreas Christensen and Olivier Giroud make way.
West Ham make five changes from their last game. Felipe Anderson, Manuel Lanzini and Marko Arnautovic are all fit again.
Chelsea (4-3-3): Kepa; Azpilicueta (c), Rudiger, David Luiz, Emerson; Kante, Jorginho, Loftus-Cheek; Hudson-Odoi, Higuain, Hazard.
Subs: Caballero, Christensen, Barkley, Kovacic, Willian, Pedro, Giroud.
West Ham (4-2-3-1): Fabianski; Fredericks, Balbuena, Ogbonna, Cresswell; Rice, Noble (c); Arnatovic, Anderson, Lanzini; Chicharito.
Subs: Adrian, Diop, Masuaku, Obian, Snodgrass, Nasri, Perez.
Today's referee is Christoper Kavanagh.
Chelsea have won nine of our last 11 home matches in all competitions, with our only defeat in that time coming against Manchester United in the FA Cup fifth round.
We have not lost a home Premier League game on a Monday since December 1994 (2-3 v Man Utd), winning 11 and drawing three since then.
No side has conceded fewer home goals than Chelsea in the Premier League this season (10) and only Arsenal and Manchester United have scored more than once as a visiting side at Stamford Bridge this season.
Chelsea have won all four home Premier League London derbies this season.
West Ham have won 15 points on the road this term in 15 games. They have won four at Everton, Newcastle, Fulham and Southampton, drawn three at Leicester, Huddersfield and Crystal Palace and lost eight at Liverpool, Arsenal, Brighton, Burnley, Bournemouth, Wolves, Manchester City and Cardiff.
Since 27 December, Manuel Pellegrini’s side have picked up one point on their travels (at Crystal Palace), losing the other five and scoring one goal (a penalty) in the Palace 1-1 draw.
West Ham have not kept a clean sheet in each of their past seven away league games.
West Ham are unbeaten in their last 17 Premier League games in which they have scored this season (12 wins, five draws) since a 1-3 loss at Arsenal in August. It is the longest current such run in the division.
