Chelsea v Villa team news: Vlaar and Agbonlahor injury doubts
Lambert will check on the star duo this afternoon as he starts formulating his team plans for the Stamford Bridge clash.
Vlaar has missed the last five games with a calf injury while Agbonlahor was absent from the Liverpool clash with a thigh problem.
Stephen Ireland, who missed the Norwich and Liverpool games with a stomach bug, will be fit to face Chelsea.
Lambert said: "I've seen Ron this morning but he's not done much at all.
"He's done a bit of running here and there but we'll see how he's doing.
"Gabby was not involved against Liverpool and he's another one who this game might be a bit too early for. We will see how Gabby is.
"If they don't come through it will more or less the same squad as Liverpool."
