Manchester United captain Wayne Rooney doesn't believe Newcastle United's derby defeat will affect them tomorrow.

Rooney does not believe the loss will be playing on the mind of the Newcastle players when they arrive at Old Trafford on Friday.

"I don't think losing to Sunderland will affect them too much," Rooney said.

"It was a big loss for them in a derby, especially with the last-minute winner but they're coming to Old Trafford to play Manchester United, so they'll be ready for it. I think we'll have to be at our best to win the game."
