I think you have to look at this in terms of pure logic.
It would have surely been an easier transition to make this decision at the end of last season, or at least during the close season. A new manager would have come in, and would have had time to sign the players that he would have wanted, for the system that he would have adopted. As it is, we'll not get someone in before Friday's transfer deadline, so now whoever comes in is going to have to make do with what he has at his disposal, at least until January, barring loans of course. That, to me, is what makes this whole saga so strange. The timing just doesn't add up. I don't doubt that the squad is reasonable, and there is plenty of potential there with the likes of Barton, Fleck and Jennings, but it may not have been what the new manager would have had in mind.
