Who do you replace him with?
Some off the names mentioned over the last couple of days are unattainable. Neither Frank or Iraola leave their current positions to come & why would they? - in time, with steps of progression, then naturally they are obtainable, but not at present.
It does seem that some, probably the majority need an honest acceptance of the current level of the club - the first aim should be to survive, and if the you cannot guarantee that the next guy in is better than the current manager surely you stick, not twist?
