Chelsea manager Frank Lampard has delivered a fitness update on defender Antonio Rudiger.
The centre-back has been missing for the Blues since suffering a knee injury in April, while he is also dealing with a groin problem.
Rudiger had declared himself fit recently but Lampard says the German is three to four weeks away from a return.
"[Rudiger] had an operation and he's going to be out for probably about three weeks hopefully," Lampard told reporters.
"Then we'll have to see how the match fitness comes in, because it's a long time Toni's been out now.
"It was nice to get something definitive about it. We've been trying to find a solution, Toni's been having some issues, and it's not easy for someone in that position.
"Hopefully we are at that case now and, in three weeks' time, we'll be in a better place."
