Villa v Norwich: Lambert - Forwards "really lively" in training
Lambert worked the trio hard at Bodymoor Heath and gave them a pep talk on the eve of the Canaries clash.
Benteke, Agbonlahor and Weimann have failed to score in the last three matches, against West Ham, Cardiff and Newcastle.
But boss Lambert is a big believer in the trio and thinks it's only a matter of time before they find the net again.
Lambert pointed to their collective performance against Liverpool at Anfield as the prime example of what he's looking for from the powerful aces.
Benteke and Weimann found the net, with Agbonlahor coming up trumps as the provider.
Now Lambert wants another inspiring performance on Sunday.
He said: "We spoke with the three of them during the week.
"They have looked really lively this week.
"They are getting into positions to score. That's the thing.
"Look at the game up at Liverpool, Christian and Andi scored while Gabby was the one who set them up. That's a proper front three performance.
"They are a handful for any team. They just need that finishing touch.
"I'm not too despondent in terms of the way we are playing. We are creating chances. We just need someone to take them.
"A lot of teams would love our front three. We just need to keep playing the way we are and turn that into goals.
"If you look at the Cardiff game, we should have been two or three up. In the first half against Newcastle, we should have had a couple of goals."
