The midfielder, 24, played a key role for Villa at Anfield as they continued their unbeaten start to the season with a 1-0 victory.
"In the two years I have been here he has been so consistent," Lambert told the club's official website. "He's a lad who probably doesn't get talked about because he makes the game look so easy.
"He's been outstanding. He makes everything look so simple. He does the easy things brilliantly. What I mean by that is he can pass a two-yard ball and never give it away - some people don't want to do that. I just thought he was brilliant."
Saturday's win over Liverpool has seen the Villans move up to second place in the Premier League table, two points behind leaders Chelsea.
