Are we sure it was definitely a written questionnaire cos I'm sure he mentioned something about having an open air chat with the players about these same points.I'm not complaining , just think it's bizarre asking them to fill in a questionnaire.
He seems a no nonsense sort so what's wrong with sitting down with them rather than fill a form in.
Like a 'no holds barred' meeting, where everyone has a clean slate so you honestly give your views about the whole situation without any consequences. Just a fresh start.
