Why are people being played out of position?

Louis van Gaal’s formation problems reared their ugly head once again.

Wayne Rooney being played in midfield does not work – this should have been sussed out weeks ago. He gets the job done as a midfielder, but he does not doing it well.

Robin van Persie even played in the middle during the game. Fellaini up top for some unknown reason. And Paddy McNair was taken off for Falcao. Can Falcao defend?!
