There's 10 of them; Vickers, O'Donnell, Nelson, Batth, Elder, Ward, Weimann, Jackson, Osborn, Rooney.

Vickers. Will he fancy another stint as 2nd keeper? If so, I'd keep him
O'Donnell. Ditto as 3rd keeper.
Rooney. An injury free season of good performances could see him get a new offer. He's had his injury issues but there's a utility player in there. CH, RB, DM, RWB. Love to see him healthy and playing to his potential and if he manages that then new contract IMO. Otherwise it's good luck for the future.

The rest, thanks for your service and good luck with the rest of your career.
