Think
Grealish needs a more free role personally but can’t see
Moyes having that.
Moyes seems like his best players on the pitch regardless of what their best position is and is quite happy to sacrifice some performance in individuals to achieve that imo.
So if he is signed,
Grealish will only ever be used in the role he has been as I think
KDH, Skilliman & Garner can do enough of a job in other places while maintaining the defensive shape / discipline to get them all on together.
Doesn’t mean I wouldn’t want Grealish on the right deal but I do have reservations about the cost of it, were it to impact recruitment elsewhere.
