That's a strange thought process you have there.
You don't understand his qualities > you don't see where he fits > why would we pay €100m if you'd only have him on the bench?
Ever thought it's more along the lines of:
Van Gaal knows his qualities > Van Gaal knows exactly where he would fit > Van Gaal is happy to pay €100m for someone he's start in every game in his favoured system.
Like with Di Maria?
Yes, I agree I don't see where he fits and Van Gaal might very well know where he fits, but to me spending 100M for Muller is a luxury signing and I believe should not be our priority right now.
