Villa v Cardiff: Lambert challenges Kozak/Helenius to step up
Kozak or Helenius - or both - could feature against the Bluebirds and Lambert is not fazed about throwing in either striker.
Lambert has been very happy with the progress made by both forwards and now wants them to step up to the plate in the coming weeks and months ahead.
Lambert said: "Gabby isn't fit. We're not so sure how long he'll be. His ankle is still bad. It's a ligament thing that's never really settled down.
"To be fair to him, he's been playing with it and we asked him to go and perform and he did it but it started getting worse and you can't keep doing that.
"Andi is still out. He'll hopefully be fine for West Brom.
"Now the other lads have got to step up to the plate.
"Football is great because the wheel always turns. You always get an opportunity to try and get in and when the opportunity is there you have to go and take it.
"It's up to the individual to go and take it.
"I have confidence in Libor and Nicklas, no doubt whatsoever.
"I think you've got to respect that it's tough being a foreign guy going into as foreign place.
"Some people hit the ground running and some people take a few months. Somebody might take a year.
"You've just got to hope that they adapt as quick as they can.
"From a managers' point of view, you've got to hope they hit the ground running but it can vary.
"The lads have definitely got better since they came into the building."
