Ernie's priority must be to sort out the spine of the team. Assuming Finkler is coming, Roly is staying and Vinnie is leaving, our priorities must be 1) an experienced commanding CB who has composure and plays with both feet in their mid-late 20s and 2) a starting, naturally central, striker.
I really don't want to be converting natural midfielders into defenders (though I could imagine Rodriguez developing into a Mascherano type role over a few years), and given our abundance of attacking wide midfielders, is Rogerson's spot better utilised by Gulley at right back?
