Mateo Kovacic, back from suspension, returns to the starting line-up.
Mason Mount is also back in the selected 11 as the other of two changes Frank Lampard makes to the side which began the Boxing Day defeat against Southampton.
Jorginho and Callum Hudson-Odoi are the two players making way. Nineteen-year-old right-back Tariq Lamptey is on the bench.
Marcos Alonso and Reece James failed to recover from injuries that kept them out of the last game in time to be considered today, and Christian Pulisic felt a hamstring training after the Southampton game and is left out as a precaution. Olivier Giroud is also injured.
For Arsenal, Calum Chambers is back in their defence after suspension to play alongside former Blue David Luiz. Matteo Guendouzi comes in for Granit Xhaka.
Chelsea: Kepa; Rudiger, Zouma, Tomori; Azpilicueta (c), Kante, Kovacic, Emerson; Willian, Abraham, Mount.
Subs: Caballero, Lamptey, Christensen, Jorginho, Barkley, Hudson-Odoi, Batshuayi.
Arsenal: Leno; Maitland-Niles, Chambers, David Luiz, Saka; Torreira, Guendouzi; Nelson, Ozil, Aubameyang (c); Lacazette.
