Hopefully we've learned the lesson of McInnes' final window here. You simply can't afford to miss one out, it sets you back two at least. We should have the structure in place where trusting Robson or not is irrelevant. We've got an independent recruitment team who can target players and the manager is just a small part of that (or that certainly seems to be our strategy - a good one). You don't need to do a great deal in a January window, just keep things ticking over with getting rid of deadwood and adding players in key positions where it's clear to everyone we're lacking. Also, identify pre-contracts and try and have them in place (preferably before the window closes, which might provoke the parent club to sell on the cheap). We're not building a squad.
Not doing this in McInnes' last window killed Glass' tenure completely. It'd be a disaster if the board hadn't learned that lesson.
