Wilson, I can see Smith perhaps playing due to necessity although grudgingly by Smith.
Fleck wouldn't be in his right mind to stay. He will never get a run up front. I would perfectly understand if he left. He will be 19 in the summer and for a prospect of his ability had to have had much more football by now. If hes in the same situation this time next year he will be officially ruined.
As I said, I expect Wilson to stay, in the current situation I think he will play quite alot - for a 18 centre half.
No youngsters will want to endure serving under Smith, its a road to nowhere.
