Aston Villa boss Paul Lambert was delighted for matchwinner Libor Kozak after victory at Norwich City.

The former Lazio striker netted his first goal for Villa after coming off the bench.

"Libor came on and to be fair it was at a difficult time. He popped up with the goal that has won us the game," said Lambert.

"He's come here, with how fast it is, and he's endeared himself to the crowd which is great."
