Chelsea boss Graham Potter says Thiago Silva's injury is an opportunity for other defenders.
Potter is confident others can step up.
"You're always going to miss a player and a person of Thiago Silva's quality, but at the same time it's an opportunity for other players," Potter noted.
"Wesley [Fofana] is coming back into the team after a long injury. We've missed him. He's a different type of person to Thiago of course, but he has qualities as well.
"It's exciting for people to emerge and develop into a role that is left vacant in terms of what Thiago brings.
"There isn't another Thiago Silva, so as a group we need to try to find a solution together. That's what the players have been working towards.
"We've had a good training week, some good feedback, some good honest conversations. I feel the support from the players and the people in the building, and we all want to improve, and that's exciting."
