The 21-year old Austrian is continuing to improve and flourish in the Premier League environment and Lambert feels it is down to his exceptional amount of running he does for 90 minutes.
"Andi must have another lung somewhere because he has a phenomenal work-rate," the Villa boss told the club's official website after Weimann netted his 11th goal in all competitions in the weekend's 3-2 win over QPR.
"That will serve him well for his whole career from now until the day he stops.
"The biggest compliment I can give him is that he's a brilliant guy and gives you everything he's got. If he keeps that he will go a long way.
"He's playing exceptionally well. I know his natural position is through the middle but whether he plays off the line or through the middle he seems to score.
"If he keeps that enthusiasm and that hunger and desire to play a game of football he will have a big, big career."
