Aston Villa boss Paul Lambert hailed Brad Guzan as "world class" after victory at Norwich City.

Guzan saved a penalty and produced an unbelievable stop at the death to earn Villa the points.

Lambert said: "Guzan was commanding. And the save from the header, where he tipped over the bar, that was world-class.

"To be fair, while I have been here, he's been so consistent with his performances. He's an absolute top lad too."
