Neither was in the squad for the 6-0 win in midweek. And Lampard suggests they could be on their way out very soon.
"The situation with both is that they weren't in the squad," Lampard told reporters post-game.
"I had a similar answer from the other day; they just weren't in the squad. That is just a choice at the moment.
"Again with the centre-halves I can't have them all in the squad. I keep getting asked about the size of the squad. There might be movement, we know that, but nothing is concrete so don't read too much into those selections at the minute.
"It will have to be things which are right for the club and individuals and me and in terms of what happens in the next couple of weeks."
