The Germany international was on the bench for his side's 3-1 win over Brighton & Hove Albion on September 14 but was not included in the clash with the Premier League champions at Stamford Bridge.
Lampard explained after the match the reason for the 27-year-old's absence, which has sparked rumours that the defender could leave the London club before the end of this summer's transfer window.
"We have five centre-halves at the club and I can't pick a squad that has three of them on the bench," Lampard told reporters. "That is the way it is, I have to pick a squad via training and situations and that was the selection today."
Chelsea signed Thiago Silva on a free transfer earlier this summer, but the experienced centre-back is yet to represent his new club due to fitness issues. body check tags ::
