Highly and he was one of the midfielders I wanted more than most for us to sign. To make it clear, if we do sign him, I'll be happy, but there are a few, not a lot, that I'd rather have for one reason or another. Vidal has shown more improvement over the course of the season and in my eyes, he'd be a better fit to what we need.
I think van Gaal won't drop Fellaini for Gündogan, because he sees his attributes, mostly his physicality, as a necessity. Gündogan isn't capable of playing as the holding midfielder yet, so what's left? Replace Herrera? I don't think he's currently better and he would compete for a spot with him, whereas Vidal for example would immediately replace Fellaini in the starting XI.
