Powell came off the bench to score in United's 4-0 win over Wigan in the Premier League.

"When I first came out onto the pitch, the crowd scared me a little bit," he said.

"I am only used to 5,000 people every now and then.

"It is a great feeling but I will keep myself on the ground."

Powell admits that he has learned a lot from taining alongside Paul Scholes.

"It is unbelievable. He has so much experience," he said.

"He came off when I came on but it was great to be on the pitch with the lot of them, especially Scholes making his 700th appearance for United."
