He needs to do something dramatic to give the transfer muppets, which we've pretty much all become now, temporarily at least, something to digest. He needs to make a statement: this is the new regime, this player represents the future and my rebuild, I know what I'm doing in the market and I can convince top players to come. It'll get a monkey off his back in the media and among fans with genuine concerns like the ones being posted in this thread. That's as good a reason to do something this month as any other, that it'll silence a lot of the speculation about our demise and give the squad a lift in terms of morale. He should really break the bank and get that done, it couldn't do any harm in encouraging Rooney to commit himself either (as long as it isn't someone who'll compete for his position, of course).
The point I'm rambling on here trying to make is that while our squad lacks a bit of quality and needs reinforcement, I think it'll do even more from a morale perspective, relieving pressure coming from those worrying Moyes simply doesn't know what he's doing. Getting someone A List in might give us more of a sense of direction and purpose.
