Watford, meanwhile, are flying high this season and will pose a serious threat to the Blues, particularly on their own patch.
Watford are expected to be without Andre Gray, while Will Hughes and Sebastian Prodl are also unlikely to feature. The Hornets have no suspensions to worry about, but they may opt to rotate the squad.
Potential Watford starting XI: Foster; Holebas, Cathcart, Kabasele, Femenia; Doucoure, Capoue, Sema, Pereyra, Deulofeu; Deeney
Position Chelsea squad
Goalkeepers Kepa, Caballero, Green, Bulka
Defenders Rudiger, Alonso, Zappacosta, Cahill, Christensen, Azpilicueta, Luiz, Ampadu
Midfielders Moses, Fabregas, Jorginho, Drinkwater, Kante, Barkley, Loftus-Cheek, Kovacic, McEachran
Forwards Hazard, Pedro, Giroud, Morata, Willian, Hudson-Odoi
Andreas Christensen is a major concern for Sarri due to a hamstring injury, but Alvaro Morata is available again. The Italian coach has a preferred XI, but may switch things up in midfield and attack to preserve the legs of his players through the festive period.
Potential Chelsea starting XI: Kepa; Azpilicueta, Luiz, Rudiger, Alonso; Jorginho, Kovacic, Kante; Pedro, Willian, Hazard.
Position Watford squad
Goalkeepers Gomes, Dahlberg, Foster
Defenders Janmaat, Britos, Kaboul, Prodl, Mariappa, Masina, Cathcart, Femenia, Zeegelaar, Navarro, Wilmot, Holebas, Kabasele
Midfielders Cleverley, Sema, Chalobah, Doucoure, Hughes, Quina, Capoue, Pereyra
Forwards Deulofeu, Deeney, Success, Penaranda, Gray, Okaka
