not every manager has the same way or style of doing things,thats why they have certain players and backroom staff they can trust and rely on,thats the way it is unfortunately or fortunately.
what do you call rosey?and no manager worth his salt is going to be told to get to work with players that he may not rate,corney might aswell pick the team.
so joe gets rid of the dead wood and builds his own team then does one after a year then we get another manager in who wants to build his own team and has a three year plan then the powers that be get rid then we get another man in with his three year plan and so on,
