Chelsea boss Thomas Tuchel says they must wait for Denis Zakaria to be available for his debut.
Chelsea will also have to wait to use their £12m signing Pierre-Emerick Aubameyang from Barcelona due to him suffering a fractured jaw during an armed robbery at his family home in Catalonia shortly before the move.
Chelsea will also have to wait before playing Juventus loan signing Zakaria, who is still waiting for his work permit and remains in Italy. But injuries have eased with only N'Golo Kante out of the match against West Ham.
“At the moment he [Aubameyang] cannot train," Tuchel said. "We have to make sure he gets a mask to protect his jaw. Then we can start to try with a mask next week.
"It's only N'Golo out. Everybody else is in training. A group of 19 players. With Auba and Denis Zakaria it will be 21 players plus goalkeepers."
Adding about Zakaria: "We need to work on the work permit. He will not be in the squad for Saturday. That is too close. We hope for Tuesday [against Dinamo Zagreb] and then for Fulham."
