Chelsea manager Frank Lampard admits he could make changes for Tuesday's meeting with Rennes in the Champions League.

Lampard named Ben Chilwell as a potential absentee after his start in the 2-0 win over Newcastle United on Sunday.

Chilwell suffered a back injury with England but was able to face the Magpies.

"I'll make a decision whether to make changes or not depending on how the recovery looks," Lampard told the club's website. "We have people like Ben Chilwell, who has had a back problem, and players who played a lot of international minutes so we'll have to see how they are.

"I have faith in the squad but when I pick the team, I'll try to pick the strongest team possible with a view to where the freshness and legs are in the group.

"We have five substitutes in the Champions League, which is obviously a big plus for us that we can make decisions during the game as well, but we know it's going to be a really tough game out there."
