Chelsea boss Antonio Conte admits Michy Batshuayi could start against Stoke City.
Diego Costa is banned for the game after being booked in victory at Crystal Palace.
Asked about Batshuayi, Conte stated: "It's not easy to arrive and understand and adapt to his league. I can see another example, Zaza at West Ham. I know him very well, he played with me at the Euros, and he is a good player, but in England he is having a lot of difficulty.
"This football is very tough, very physical. Michy has good quality, he's very young, and it's important for him to continue to work and improve, and I think this season he can have a good satisfaction."
