Chelsea trio Romelu Lukaku, N'Golo Kante and Christian Pulisic are all doubts due to injury.
Emi Martinez will miss a league game for the first time since joining Aston Villa because of quarantine rules, along with Emi Buendia.
Leon Bailey, John McGinn and Jacob Ramsey are available, while Bertrand Traore has returned to training.
LAWRO'S PREDICTION
I was impressed by Chelsea in their draw with Liverpool before the international break - they were the better side with 11 men and they still did well when they were down to 10.
Aston Villa won't lack energy or effort but the Blues should be too strong for them.
