Im with the general consensus I think; a left sided player who is good enough to start games and a 'captain material centre back' are top of my wish list.
If Bunney doesn't leave, then he can fill the left sided player gap.
I have a gut feeling that Andy Williams will leave, if he doesn't Im struggling to see how he is going to be involved much unless Smith gets injured.
All on the assumption that KC is going to set us up with wing backs.
I agree with the 'captain material centre back' and left sided playing starter.
A rough guide to the squad with 'two-players-for-each-position' in mind:
GK: Arnold/Cornell
DF: Adams/Hall-Johnson; Martin/Bunney; Turnbull/Goode/
New CB/Williams
MF: Lines/McCormack/Watson/
New LM-LW/McWilliams/Warburton/Hoskins/Pollock
FW: Smith/Williams/Morias/Oliver
So 2 more in (at least), plus 1 more for each departure from those above.
I think Waters will leave, even if only on loan, and he won't need to be replaced.
