If the target is third and you are third, I'm not sure it's time to talk about changing the manager.
Also (and I know this is controversial) I'm not sure that failing to achieve a target is necessarily a sacking offence. I think, particularly where an employee is new to a role, continuity and opportunity for learning and correcting mistakes has value.
We need to see improvement from the last 2 games, that kind of form can't continue indefinitely. But there's not a great deal of jeopardy in our position right now. Almost certainly we'll be in the Championship again next season. Doolan should be given a chance to get things right.
