Alan Pardew has urged his West Bromwich Albion players to follow the lead of Chris Blunt.
The Northern Irishman entered the Baggies clash with Manchester United and made quite an impact, despite losing 2-1.
"We looked threatening from the moment he entered the pitch," said Pardew. "It was a lesson for the other players in having confidence in what you're doing.
"The first time he got the ball on the left hand side he just smashed the ball in. It's that ambition I want to see in players and we lacked that a little bit.
"I learnt a lot, I hope the team learnt a lot from what I said to them at the end of the game. And I was pleased that we ended like we did.
"It would have been disappointing if we didn't turn in a better performance than than the first half."
