The 21 year-old has made a big impact since his summer arrival.
Agbonlahor told Villa's website: "From his point of view he is still learning because he's only 21 but it was big credit to him to get the winning goal.
"He reminds me a bit of John Carew when he came here - the way he holds the ball up, is strong, good in the air, got a bit of pace. He's got all that.
"I think he can be as good as he wants to be. If he takes in what the coaching staff help him with and the experience players, I think he can be unplayable.
"He is unplayable at the moment but he can be whatever he wants to be."
