Manchester United midfielder Michael Carrick has played down his role in yesterday's derby winner scored by Wayne Rooney.

He recalled on MUTV: "I think Ji-sung Park headed it down and I just got a shot away as quickly as I could.

"It was nice for Wazza to get a tap-in and set us on our way.

"[Scoring 100 club goals] is a great achievement, especially when you consider how old he is. You forget how young Wayne is sometimes."
