Does Van Gaal see Herrera as a starter or a sub?

Ander has been featuring on the Manchester United bench a bit more frequently than he is in the starting XI which is cause for concern.

But, Herrera proved his worth within his first minute of coming on as a substitute. One of his first touches went to James Wilson, who then ran up to score the third goal against Cambridge.

Herrera should start against West Ham United for that alone!
