Manchester United legend Andy Cole feels Wayne Rooney is primed for a big derby at Manchester City.
Rooney returns from suspension for Sunday's trip to the Etihad.
"He has got to be raring to go," Cole said.
"He is a professional footballer. When you miss games through injury or illness or suspension, you are going to be disappointed.
"It's going to be a massive boost to have a player of his quality back.
"Hopefully we can go to Man City and get a positive result."
