Chelsea's Mateo Kovacic is fit after a five-week absence with a hamstring problem, while N'Golo Kante will start despite nursing an Achilles issue.
Leicester will assess the fitness of defender Jonny Evans, who has missed two games because of a heel injury.
Ricardo Pereira and James Maddison may not be risked from the start as they continue to strive for full fitness.
