If you survive (as seems more than likely) and if you manage to bring home some silverware, then, I think that much of the criticism that has been directed at David Moyes this season has been excessive and somewhat unwarranted.
Everyone wants to see stylish, attractive, attacking football, or even the sort of pressing game where you play out from the back; but, firstly, one must prioritise survival, and secondly, one must play the players one has (or has been able to buy, or develop), and not all of them are capable of mastering these styles in a way that can deliver a decent result against teams with a bottomless purse.
If the season leads to some silverware, then, I think that you may have to class it a reasonably successful one.
