I think Rooney's passing is underrated. He obviously would never be a possession midfielder but then that's not the point. You don't put Rooney in midfield and ask him to play like Leon Britton. You have him in there to compliment the other midfielders. His passing is as good as most box-to-box midfielders that spring to mind. He also has the strength, work rate, aggression, drive, defensive awareness, footwork, vision, close control, dribbling skill, shooting skills etc etc (the list could go on) that would compliment Kagawa (or Mata's) skill set. It's all about balance, innit. Rooney would contribute to our attacking play whilst also relieving Kagawa (or Mata) of some of their defensive responsibility, so they can concentrate on the old play-a-makin' shtick.
