GK: Lewis, Roos. Won't be signing anyone else here.
RB: Richardson. Could do with one, even allowing for McCrorie as back up for RB.
LB: MacKenzie, Ngwenya. Can't see us signing one with Hayes also there but would love a first pick LB to be brought in.
CB: Stewart, Bates, Scales. Think we need another one here unless one of the youngsters is deemed ready.
CM: Barron, Polvara, Ramadani, McCrorie. Definitely a couple needed here and apparently being pursued.
Wing: Vicente, Kennedy, Hayes, Duncan, McLennan. Think we need at least one more here as well but don't know if it'll be a priority.
CF: Bojan, Watkins, Harvey. Think we'll need at least one here.
That's a 20 man squad as it stands - 21 if a young CB is being brought into the first team - assuming Ferguson and Ramirez go.
Still work to do and you can see why Goodwin might want four more.
