The Blues will be permanently without wing-back Ben Chilwell, who is a long-term absentee with a knee injury, but the rest of the squad could feature.
Chelsea had sweated over the fitness of Hakim Ziyech and Mateo Kovacic after limping off in Wednesday’s Champions League win over Lille, but both are back in training.
The same goes for midfielder Mason Mount, who suffered an ankle injury in the Club World Cup final earlier this month. It remains to be seen if Romelu Lukaku will be reintroduced in the line-up.
Chelsea could be further boosted by the return of wing-back Reece James as he returns to training after recovering from a hamstring injury picked up in December.
James is most likely to make the bench on Sunday, with Chelsea boss Thomas Tuchel hinting he wants to be careful and not rush him.
“Let’s wait for another session and see if I’m crazy enough to put it on the court, or if my reasonable side wins in the end and we go step by step,” he said.
“It would be a big step forward, but honestly, yesterday and today he looked so strong, so confident and so involved in training that you’re tempted to do that.”
Tuchel is yet to decide who will start in goal on Sunday. Edouard Mendy is Chelsea’s No.1, but Kepa Arrizabalaga has started every round of the Carabao Cup this season.
Chelsea predicted XI: Kepa; Christensen, Silva, Rudiger; Azpilicueta, Kante, Jorginho, Alonso; Mount, Havertz, Pulisic.
