Wayne Rooney: We knew Marouane Fellaini was quality

Wayne Rooney never doubted Marouane Fellaini would become a world-beater at Manchester United. 

Fellaini put on the latest in a long line of impressive performances on Sunday when he starred in United’s 4-2 derby win over Man City at Old Trafford.

Fellaini did not start a game for United until the end of October, but his form has become so good those who work with him have been falling over themselves to praise him.
