Lambert was thrilled with the display of the Dutch ace at Upton Park.
He told Villa's website: "We played Leo over on the left.
"He hasn't played there before but he did fantastic for us. He was up against the lad Stewart Downing. I thought he did fantastic for us at left-wing back. I think he did great.
"In a game of this magnitude, I thought he did really well.
"That was one of a few big performances out there."
