Chelsea make three changes from the team that drew 2-2 with Everton before the international break, with Graham Potter appearing to switch to a back four.
One of them is enforced as Wesley Fofana is ruled out with injury, so Marc Cucurella comes in at the back.
The other two changes see Ruben Loftus-Cheek coming in to replace Benoit Badiashile, while Mykhailo Mudryk replaces Christian Pulisic on the wing.
As expected, Mason Mount is on the bench after missing international duty with England, with N’Golo Kante also among the substitutes.
Chelsea: Kepa; James, Koulibaly, Cucurella, Chilwell; Enzo, Loftus-Cheek, Kovacic; Felix, Havertz, Mudryk
Substitutes: Bettinelli, Badiashile, Kante, Pulisic, Chalobah, Mount, Gallagher, Chukwuemeka, Madueke
Aston Villa: Martinez; A.Young, Konsa, Mings, Moreno; Kamara, Luiz, McGinn; Buendia, Watkins, Ramsey
Substitutes: Sinisalo, Wright, Carlos, Traore, Chambers, Duran, Digne, Bailey, Dendoncker
