There is no Thibaut Courtois so Willy Caballero, one of the heroes of Wednesday’s penalty shoot-out, continues in goal. Courtois got a knock on his ankle in training and will be monitored over the next few days.
Gary Cahill, Cesc Fabregas, and Danny Drinkwater are all absent, so Andreas Christensen is flanked by Cesar Azpilicueta and Toni Rudiger in defence, and Tiemoue Bakayoko partners N’Golo Kante in all-France midfield ahead of them.
Brighton boss Chris Hughton makes five changes after their defeat at West Brom last time out.
Chelsea: Caballero; Azpilicueta (c), Christensen, Rudiger; Moses, Bakayoko, Kante, Alonso; Willian, Batshuayi, Hazard.
Subs: Eduardo, Zappacosta, Sterling, David Luiz, Ampadu, Barkley, Musonda.
Brighton: Ryan; Schelotto, Duffy, Goldson, Dunk (c), Suttner, Propper, Stephens, March, Gross, Hemed.
Subs: Krul, Hunemeier, Rosenior, Kayal, Izquierdo, Baldock, Murray.
Today’s referee is Jon Moss.
