Fair enough, so it's more a case of Moyes not showing he's capable than doing something you disagree with? That's a fair view. The major issue with Moyes is that he doesn't have that top level experiance, so I can see why people would be hesitant/wary of putting faith in him. Personally it doesn't bother me because I think he's capable of making the step up. He's proven himself to be a great and consistent manager, so the lack of managing a big team doesn't change that for me. But I can understand why others wouldnt have the same confidence.
In terms of what he's actually done though then surely you can't see anything majorly wrong? He has a good transfer record, manages to get the absolute most out of players, has a well drilled and organised side, consistently overperforms, handles the press well enough, develops players well and seems to give youth a chance.
With Mourinho he has that big team experience in abundance, but there is a big aspect of his management that is easy to diagree with. He seems to always want to spend huge somes of money and quite often pisses it away, he tends to play conservative football despite having an absurd amount of talent, doesn't promote youth players and acts a dick in the media.
