Chelsea received a fitness boost when Gary Cahill was able to train after leaving Wembley injured on Sunday night, but fellow defender David Luiz was a real doubt with the hamstring problem that forced him off on a stretcher.
Lampard said: "Luiz might be fairly bad but Cahill will be all right. Fortunately we have back-up.
"Branislav Ivanovic is suspended for the league games but he will be around to face Barcelona.
"It is a shame for David personally and for us as a team because he is such a good player."
