Chelsea expect to have midfielder N’Golo Kante back for the Carabao Cup tie against Southampton.
Kante missed the 7-0 Premier League win over Norwich on Saturday because of concerns over a slight muscle tightness.
Southampton forward Mohamed Elyounoussi will miss the trip to Stamford Bridge as he recovers from minor hand surgery.
James Ward-Prowse will serve the last of his three-match ban following a straight red card in the Premier League defeat at Chelsea on October 2, while on-loan Blues forward Armando Broja is not eligible to face his parent club.
Midfielder Stuart Armstrong could come in for a start, while Brazil defender Lyanco, full-back Yan Valery, forward Shane Long and goalkeeper Fraser Forster should all feature again.
Chelsea provisional squad: Arrizabalaga, Chalobah, Chilwell, Christensen, Sarr, Kante, Loftus-Cheek, Niguez, Ziyech, Havertz, Hudson-Odoi, Bettinelli, Azpilicueta, Alonso, James, Rudiger, Silva, Mbuyamba, Barkley, Mount.
Southampton provisional squad: Forster, Lyanco, Perraud, Salisu, Valery, Armstrong, Redmond, Djenepo, Tella, Diallo, Long, Lewis, Livramento, Walker-Peters, Bednarek, Romeu, Walcott, Adams.
