Villa's biggest win since 2008 not only took them five points clear of third-bottom Wigan in the battle to avoid the drop, it also improved their goal difference to the extent they overhauled Newcastle.
Lambert had Benteke to thank following his second-half heroics, which underlined why the Belgian is one of the most sought-after young players in the game.
"You can't speak highly enough of him," said Lambert. "He keeps his feet on the ground and is hungry to have success as a footballer.
"I thought we needed a striker like that. He is a big lad and everyone can see his technique is fabulous.
"He played a lot games for Genk. He is Belgium's main target player and they are going to qualify for the World Cup.
"People forget he is 22. He has a big career in front of him as long as he keeps working hard."
It still was not enough for his manager to select him as Villa's stand-out performer on a dream night.
"He was alright but Matt Lowton was the best player on the pitch by an absolute mile," he added.
