No, I think if Moyes struggles with the job it might have crushed Martinez. Just my opinion. I think Moyes will come good and I well remember how exposed Ferguson became just before he started to turn things around. I think the Fergie experience will give Moyes more time than he may have been given usually.
I also think he has a very poor squad, probably the worst since Fergie took charge. Having said that, had the gone for and got Ozil I think they would have had one hell of a team.
