Chelsea will have Cesar Azpilicueta for Tuesday's Champions League last-16 first leg against Lille.
Blues skipper Azpilicueta has bounced back from a groin injury.
Mason Mount returned to training on Monday and could be in the squad for clash at Stamford Bridge, however, it is unlikely he will start.
However, Callum Hudson-Odoi has not recovered in time from an Achilles problem.
"Azpi looks much better than Callum," said Tuchel at his pre-match press conference.
"Callum did not train yesterday but Azpi trained and had no reaction so if it stays like this then he's available for tomorrow.
"Mason did a very good individual session. He will try to come back to team training today but he was out maybe a little bit too long to start. Perhaps he is involved with the squad but he has not trained with the team yet."
