The London derby is crucial for the Blues, who have followed up their 17-game unbeaten run with back-to-back losses on the road.
A 1-0 humbling at Everton ended their streak, before Wolves came back from behind to beat them 2-1 in midweek.
As a result, at the time of writing, Chelsea have slipped to eighth place in the Premier League table, nine points away from holders Liverpool.
West Ham are, in fact, right behind Chelsea with 21 points. The Hammers enter this match-up with three wins and a draw from their last five games. Chelsea will have their task cut out once again.
West Ham will also take confidence from the last time these two sides met at the Bridge, when a hard-earned 1-0 win sank the Blues.

Chelsea vs West Ham Team News
Chelsea are short-staffed in the wide areas of the forward line, with Christian Pulisic the only recognized winger currently fully fit.
The likes of Callum Hudson-Odoi and Hakim Ziyech are back in training, but whether or not they play any part remains doubtful. Chelsea have no other fresh injury concerns.
Doubtful: Hakim Ziyech, Callum Hudson-Odoi
Arthur Masuaku's knee injury is a serious blow for West Ham, as they will miss the full-back's combative style going forward.
Michail Antonio is another huge doubt after having missed out on the team's last three games, while Fabian Balbuena is most likely out with a knock.
Injured: Fabian Balbuena, Arthur Masuaku
Doubtful: Michail Antonio
Chelsea vs West Ham Probable XI
Chelsea predicted XI (4-3-3): Edouard Mendy; Reece James, Kurt Zouma, Thiago Silva, Ben Chilwell; Mateo Kovacic, N'Golo Kante, Mason Mount; Christian Pulisic, Olivier Giroud, Hakim Ziyech
West Ham United predicted XI (4-2-3-1): Lucasz Fabianski; Vladimir Coufal, Issa Diop, Angelo Ogbonna, Aaron Cresswell; Declan Rice, Tomas Soucek; Robert Snodgrass, Said Benrahma, Pablo Fornals; Sebastian Haller
Chelsea vs West Ham Prediction
Home comforts and the likely involvement of Hakim Ziyech at some point in the game, if not from the start, should see Chelsea return to winning ways.
They will, however, have to move the ball quickly and make dangerous runs inside channels due to the massive presence of Rice and Soucek in the middle.
Prediction: Chelsea 2-1 West Ham
