I like the guy and he has been a good professional at United. I just struggle to see where exactly we would use him if he were to stay.
We're more likely than not going to be playing with something that resembles a midfield of Casemiro + Eriksen + Bruno. Eriksen and Mount will be the ones vying for the same spot. So, unless we're thinking that Scott is rotated in with those two, then he has to be playing in either spot occupied by Bruno or Casemiro. I can't see us using him in Bruno's spot, and he doesn't really have the qualities for Casemiro's spot either.
I've said it once already in this thread, but I honestly think we're more likely to keep him if we don't get any cover for Casemiro. It seems to hinge around whether or not we end up with Amrabat or not. If Amrabat comes, then there's a bigger chance of Scott going.
My preference would be to move Scott on and get in at least one other midfielder. E.g. someone to cover Casemiro.
