Moyes will be fine. Manchester United will be fine. He will get time no matter how many 'Moyes out' threads are in the forums. It is unfair to judge the man on half a season. He has already started rebuilding the team. He is starting to get rid of the deadwood that should have gone a season or two before. The old guard will slowly move on i.e. Rio, Giggs, Vidic etc and the new core of the team has already started to take shape. Moyes is learning on the job. He has not had this experience before, even Mourinho would have struggled to replace a manager like SAF.
Why does a manager who has not won anything, but has been touted as an excellent manager on these forums and by his peers for what he did at Everton suddenly become a bad manager over a few bad results? Moyes has even received backing from his colleagues such as Arsene, Jose, some of the biggest managers in the world that have praised his work yet fans believe that is all complete bollocks and they are only saying that to keep him in the job so we don't threaten for the title.
Managers who are not deemed as 'world class' i.e. Jose, Arsene, rarely get a chance of managing a top club in the world. If they do, then unless success and results are achieved quickly then they generally get the boot. Even Roberto Di Matteo did not last barely half a season after just winning Chelsea the champions league the previous season. I just think it is too early to get rid of Moyes. This is not a normal circumstance, and he deserves time to get things right. I look forward to seeing the team push for a top 4 spot this season and then look forward to who comes in and goes out the door in the summer.
