Turning to the vexed question of formations and Micky's fondness for 442.
I have some reservations that we've got the players for 442 in Morris' absence. The two youngsters have found it difficult standing in for Kieron and I'm doubtful Chalmers has the defensive skills to be able to cope with that role at present. Could Lewis or Nolan play there and how effective would they be? Other possibilities would be pushing JDC up and moving O'Connor to right-back or switching Josh Hawkes to the right and using Merrie on the left. I'm unsure we've got the squad for a 4 diamond 2 either.
4231. I doubt would work with the current personnel. Can't see Hemmings functioning effectively as a lone striker, Mumbongo even less likely, so Saunders probably the better candidate, although given his inability to get off the mark in a more conventional role, perhaps the wrong time to ask him to try.
433 seems like the best switch to look at. It seems that there are enough players capable of filling the midfield three, though the front three would be harder to blend
Finally Micky. It's not known how big a role he had in the summer recruitment, so can cut him some slack on that. However I don't accept that it was only going to be minor adjustments from last season, ideally we needed a keeper, left-back central defenders, midfielders and a striker. The financial reality was we needed to switch to a development model and there's already been some gain with the January window. Losing JDC in the summer is the last of a line of players like Ihiekwe Cook and Norwood. However in the January window, Micky was the one controlling the player movements, subject to budget constraints, so he has to own those decisions such as not replacing Doohan and concentrating on midfield recruiting when our defence had been depleted to the extent appearance for Jameson are inevitable.
