There is no way of knowing if we would have been better or worse off that is true.
What is true is that changing managers without giving the incoming manager any fucking money is not much short of fucking suicidal. Support the team, don't support the team. Seems a comment better directed at the board.
What kind of tangible progression was likely anyway without any fucking money? Change managers every fucking year if you like, every fucking week like Have I Got News For You change presenters, if there's no money to bring in better players and keep the ones we have the job is on it's arse. It is pretty fucking simple, so spending a shiteload of cash on a new manager without backing that manager financially is a risk not worth fucking taking.
