with what money?
Seems that anyone remotely decent would want a (relatively) hefty paycheck, and added to that would want some kind of budget to bring in his own people (or at least the budget to pay off contracts to get rid of some people). Say what you will about a "competitive budget" but free transfers, loanees and non-league players indicate that there's perhaps a bit of stretching of the definition of "competitive".
Add to that you're going to have to give the new guy time. No one is going to take the position in January with instructions to "finish mid table". They'll probably be more towards "avoid relegation".
I would love to see a manager come in, who without any transfers and no budget, can magically get the players to gel and play consistently well for the entire season, however I'm not holding my breath.
We're already cash flow negative, so anything that increases that deficit won't happen.
