The crux of the issue is we've signed enough players since Van Gaal joined to more or less build a squad from scratch...and yet despite that we can't even field a first team without players in the wrong positions, or who aren't good enough.
It will also be interesting to see what happens when Rooney gets injured, or Smalling (I would also say Jones, but guess what?)...and by "interesting", what I actually mean is "painful"
We all know right now, more or less for a fact, that Rooney will get injured at some point, and Carrick will be playing at centreback next to Blind at some point.
At the same time, no one, including any of our goalkeepers, knows who our goalkeeper is.
When you spend a quarter of a billion pounds to "fix" your squad, signing an entire new squad in the process, it is not in my opinion excusable to end up with a massive mess instead of a squad. You should have a squad of players, or failing that at least have assembled some kind of suicidal Fifa Ultimate Team
