You are, of course, entitled to your opinion but I do think Fergie must take some of the blame , no matter how small
Yes, and I think my opinion is the right one

People who complained seem not to realise it is a tough job at United. Fergie has set the bar so high yet he himself knows it is not an easier job to find a successor who can be passed the torch. Getting a high profile manager who has the credential to succeed him is easy because there are no shortage of willing candidates. But that manager has also need to have the character and willingness to stay in a club for a long long time.
Moyes' credential seemed (to him) to fit the bill in the sense that if he's staying in United long enough and was given the money to spend he would be able to build a team another level of Everton.
Little did he (Fergie) know Moyes was skipping the learning process (firing back room staff and insisting on using his mediocre mentality in managing his players, breaking all the United records etc.)
Fergie has spoilt United fans for many years, and fans expect him to do magic (his management skill is top notch, hence his choosing of his successor must also be top notch). He's a magician but he's not God. When we are now 7th and out of Europe next year, if Fergie is not heart broken, I don't know how he would have felt.
Blaming him is like biting the hand that feeds you. Without Fergie in the first place, what kind of glory we fans have been enjoying for so many years? Without him, we wouldn't be feeling disappointed we are not in Europe next season (because for 19 years we were never out of it). Without Fergie, we wouldn't be feeling aggrieved we were not challenging title/being top 4.
But no, fans thought Fergie, when retiring, should have appointed someone who is perfect. If it is not the case, it's his fault. Hindsight is 20/20 and he is not a God (albeit Godlike)
