There are many theories arising as to why a Manchester United team that lifted the Premier League at a mere canter last year, are struggling to look like top ten contenders only a few months later.
The one prevalent idea though is a bitter truth that Sir Alex Ferguson's presence consistently staved off; United don't actually have a great team anymore.
What Moyes was left to work with is a fairly average squad by all accounts, one that came with massive expectation and pressure, but one that had only enjoyed so much success because of his predecessor, not because they were world-beaters.
It's no wonder now then that the man charged with the impossible task of continuing Sir Alex's great legacy is faltering at the first hurdle.
The truth behind's United's woes can only to some extent be put down to the fact that the club is in transition.
The most pivotal problem, and the one that has rendered them so far incapable of rising to their usual place of residence at the Premier League's summit, is that there are more players in the United squad that aren't good enough to be there than there are figures who are really influential enough to command a spot.
A portion of the blame can be seen to have Moyes' name etched into it by way of his lack of awareness and initiative in the transfer window, but the acquisitions of Leighton Baines and Ander Herrera would have hardly put them on par with their rivals in terms of individual footballing quality.
So Moyes is left with one option; he needs to make this lacklustre United team his own, and he needs to ensure that every player taking to field in his starting XI is good enough to win the title.
Whereas Ferguson had a unique ability to take average players and install a heart, desire and team ethos that drove them at startling speed towards success, Moyes must opt for the more conventional route of simply ensuring his charges look good on paper, as well as on the pitch.
First off, there's a hell of amount of deadwood that needs to be flogged if the United ship isn't going to sink without a trace.
The naysayers and regular weekly critics can point the finger at the likes of Ashley Young and Tom Cleverly, but there are areas of the team that have avoided the purge put forth by the horrific start to the season that are just as much at fault.
Of course with the various outgoings there's also a dire need for new faces to arrive.
Rio Ferdinand, Nemanja Vidic and Patrice Evra look someway off the pace this year and, although it is early doors and it's premature to be instigating talk of retirement, the United defence needs an injection of youthful quality.
The midfield could also do with a refurb. Marouane Fellaini goes some way to giving United an advantage over most when partnered with Michael Carrick, but there's far too many flaws on either wing to be saying that they are done and dusted in the transfer market in this respect.
In truth Moyes will face his biggest challenge yet come January. It's not so much naive as utterly foolish to suggest there'll be changes left, right and centre in the next window, but the former Everton coach needs to stamp his authority down and begin his rebuilding process.
As has been highlighted frequently over the course of the last few days, United must tread carefully now to avoid repeating the historical fall from grace their arch rivals Liverpool suffered, ironically a turn of events they managed to capitalise upon.
