He looks knackered. When he plays alongside Rooney (or deeper alongside Maynard) he ends up having to do the donkey work. Collar or Keane alongside him in a 2 man DM format or even a central partnership is far more fluid and the workload is shared.
We look to have gone 3-5-2 / 3-4-3 so as to accommodate both Madden (as an attacking midfielder) and Rooney. Madden brings so much more linking the front 2 and the wing backs, his football brain will improve everyone around him. Rooney scores fantastic goals every few weeks.
