As I only saw the highlights, so I can't really speak to Ander's performance last night. It sounds as though he was awful in the first half, but a goal and an assist on his return to the starting XI looks a solid return to me.
I'm surprised that Herrera was so effective at 10. Personally, I think he's more of an eight. Still, as the Van Gaal quote from
@Shimo shows, we're playing two sixes and one 10, so there's no number eight position for him to play. If Herrera is going to get back into the team its gonna be in the Litmanen/Muller role. With the way Herrera's goalscoring has (surprisingly) blossomed since he joined United, who is to say he can't make that role his own?
