The Belgium international has enjoyed a superb first season in the Barclays Premier League, hitting 19 goals for his club in all competitions.
Benteke, who is supposedly attracting interest from so-called bigger clubs, has been shortlisted for the PFA's Young Player of the Season award - but Villa boss Lambert showed little interest in the nomination.
"I'm not bothered if he's nominated or not, as long as he's performing for this club," said the Scot. "That's the most important thing for me.
"His form has dictated that people have nominated him. It's great for him and great for the football club that he has been, alongside some really great players.
"Whether he wins it or not, wait and see. I don't think it will affect him one bit or affect his football. If he remains the way he is at this minute, he'll do very well for himself."
