But that is half the transfer window gone. Would he be allowed to work with the recruitment team prior to officially taking up the job
Maybe not, but surely they'd be heavily involved in incomings and outgoings as soon as the window opens.
Again as I said on another thread, whoever we get in is unlikely to have worked with any of our players before, and will not see them in action before they return for pre-season training. Realistically, no new manager is going to be in any position to make any decisions on any of our players until mid-July at the very earliest, as early pre-season doesn't involve much kicking footballs about.
I can only assume that Dan Ashworth is going to be quite influential in any player signings before then, as well as accepting/rejecting any bids too.
