Chelsea captain John Terry will miss Sunday’s FA Cup fifth-round tie with Manchester City with a hamstring injury.
Midfielder Oscar returned from a calf injury in the midweek Champions League loss at Paris St Germain and could come in to start, perhaps at the expense of Eden Hazard.
Midfielder Nemanja Matic is available following his European suspension, but Alexandre Pato is still short of match fitness and Kurt Zouma (knee) and Radamel Falcao (thigh) are long-term absentees.
Provisional squad: Courtois, Begovic, Blackman, Ivanovic, Fabregas, Rahman, Oscar, Hazard, Mikel, Traore, Kenedy, Pedro, Remy, Costa, Miazga, Matic, Willian, Cahill, Azpilicueta, Loftus-Cheek, Clarke-Salter.
Manchester City boss Manuel Pellegrini looks set to play a weakened, youthful-looking side against Chelsea in their FA Cup fifth-round tie at Stamford Bridge on Sunday.
Pellegrini has concerns about the effects on the fit members of his injury-ravaged squad at the start of a week that also includes a Champions League trip to Dynamo Kiev and the Capital One Cup final at Wembley.
Defenders Bacary Sagna and Eliaquim Mangala, midfielders Samir Nasri, Kevin De Bruyne, Fabian Delph and Jesus Navas, and striker Wilfried Bony are all sidelined.
Provisional squad: Caballero, Hart, Zabaleta, Kompany, Demichelis, Otamendi, Humphreys, Angelino, Kolarov, Clichy, Toure, Fernando, Fernandinho, Sterling, Silva, Celina, Barker, M Garcia, A Garcia, Glendon, Aguero, Iheanacho.
