McLeish revealed his delight at seeing Bent firing on all cylinders again.
The Villa boss told the club's website: "People think it is easy. They think that England tap-in the other night was easy and that you could place anybody in that position and they would surely score.
"But with Bent it is about his movement and his uncanny nose for space.
"Of course he needs to get the ball delivered to him and that takes another kind of skill from other players.
"But Benty has essentially scored the goal that gave England the point to qualify.
"He is in great form, he is high on confidence, his fitness is much better and he looks much sharper to me."
