The 22-year old Belgian striker netted a double and supplied an assist for Andreas Weimann in Villa's 3-1 win at Liverpool on Saturday, prompting Lambert to praise the £7million summer signing from Genk.
"I have seen that sort of thing all along," Lambert told the club's official website about Benteke who has scored eight goals in all competitions this term.
"You run out of things to say about the big guy. He's unbelievable. He's 22 and he can be anything he wants. He's a top lad too which is important.
"His partnerships - whether it's with Andi (Weimann), Darren (Bent), Gabby (Agbonlahor) - it seems everyone likes playing alongside him. He's been sensational for us.
"There aren't many can push him off the ball that's for sure. He's got the potential to be one of the best.
"I don't want to put too much pressure on him but the potential for someone as young as that is an absolutely frightening thought."
