Sunderland v Villa injury news: Benteke back in training
Benteke trained with his team-mates this morning and could feature in the New Year's Day clash at the Stadium of Light.
The 22-year-old has been nursing a knee problem that has kept him out of Villa's last three Barclays Premier League games.
Meanwhile, Lambert is also keeping tabs on the fitness of Ron Vlaar, who did some light training this morning as he steps up his recovery from a calf injury.
Vlaar hasn't featured since being forced off at half time during the 3-2 victory at Southampton on December 4.
If the skipper is able to feature, it will be a timely return with fellow centre-back Ciaran Clark set to serve a one-match suspension.
Joe Bennett is also on the road to recovery following a long spell on the sidelines with a back injury.
"Christian trained this morning and he looked ok," said Lambert.
"He feels ok within himself. He's back and hopefully he'll go and do what he did for us at the tail end of last year, which is when Christian started to score all of his goals - at the turn of the year."
Asked about Vlaar, the Villa boss added: "He's looking ok at the minute. We'll see how he is and judge it tomorrow."
