Thomas Tuchel admits he is worried about N'Golo Kante and Ben Chilwell.
Chelsea claimed an emphatic 4-0 win over Juventus on Tuesday.
However, both Kante and Chilwell suffered knee injuries and were forced to leave the game prematurely.
"It worries me because he was in such a fantastic moment - like Reece (James) on the other side," said Tuchel of Chilwell in his post-match press conference.
"They were in the best shape they could possibly be, so strong and so confident and with such a lot of quality.
"He was in a lot of pain, now he feels a bit better. He has an examination tomorrow (Wednesday) to be more precise. Hopefully we get away, fingers crossed, with not too bad news.
Tuchel added: "With N'Golo, it's a bit the same.
“He got stronger and stronger in the first half but twisted his knee a little bit. Hopefully it's not too bad."
