Chelsea manager Frank Lampard has said he will continue to manage Thiago Silva's workload.
The 36-year-old sat out last week's trip to Krasnodar, but returned for the Premier League win over Burnley on Saturday.
Silva will be in contention to face Rennes, if Lampard decides against resting him again.
Asked how important it was to manage Silva, Lampard said: "It's very important. Within the squad, you try to have standards and we talk to the sports science team, some is in my eyes and talking to the players.
"The honest conversation with Thiago is very easy. He is such an experienced player. At the back end of your career, you have to manage the training."
