Chelsea:
The Blues can move joint-second in the league standings with a win over Southampton tomorrow.
They should be boosted by the return of Alvaro Morata, who missed the midweek win at Huddersfield through fatigue and with a back problem.
Meanwhile, David Luiz remains sidelined with a knee problem.
Southampton:
The visitors may have been unlucky to draw at home to Arsenal last weekend, but they come into this game on the back of a 4-1 thrashing from Leicester at St Mary's.
Mauricio Pellegrino does, however, have a fully fit squad to choose from for his side's trip to the champions.
Recent form:
Possible lineups:
Chelsea: Courtois; Azpilicueta, Christensen, Cahill; Zappacosta, Fabregas, Kante, Bakayoko, Alonso; Hazard; Morata.
Southampton: Forster; Stephens, Yoshida, Van Dijk, Bertrand; Romeu, Hojbjerg; Ward-Prowse, Tadic, Redmond; Austin.
