Contrary to many opinions I agree with a lot of things the OP said. I think it is a quite interesting thread.
I think the owners are at fault. I believe that they didn't prepare properly for when Sir Alex arrived. I think a Director of Football should have been appointed before Moyes, he should have been there in Sir Alex last season but during that season just as more of an observer and planner and asking as many questions of Sir Alex and absorbing as much information as possible for when Moyes took over, by doing this I believe that a lot of problems which are occurring presently wouldn't be happening.
I think the owners shouldn't have given Ed so much power on the footballing side as I think he is trying to use the club to turn himself into a minor celebrity and if the Director of Football had been brought in, my opinion is that we wouldn't have been in such a mess as he would have made sure there was a continuity in style when a new manager came in and I believe we wouldn't have wasted all those millions.
The board are guilty of lettting Ed handle the transfers and cocking up by bringing in managers with different styles who decide 'x' amount of players don't fit my philosophy so they have to go and we have to spend 'this' many million to replace them.
Although I would say the board have invested the money, it hasn't been invested properly in my opinion, which goes back to need for a'good' Director of Football, not a 'yes' man for Ed as I don't want him near any transfers. I personally think the board should have invested more but I can see that they see it as a business and seem to be happy for top 4 as long they can keep lining their pockets.
Although I'm no big fan of Jose I think that he should have backed all the way in the summer or they should sacked him, that way he wouldn't have an excuse to moan about not having his players and resorting to his childish antics. Since he didn't get his players he should have been a man and took it on the chin and got on with it and tried to make better use of the players at his disposal instead of throwing them under the bus. He should be doing better with the players he has got and in my opinion no way should we be where we are now in the league.
I think we need a new manager as I am sick of all the negativity surrounding Jose but just by getting a new manager and giving him £300m or whatever is not going to sort out our problems. We need a Director of football in place before the new manager and hopefully the board will realise and learn from the mistakes of the last few years.
For the record I am neither a lover of Jose, Ed or the Glazers and they all need to take some responsibility for the mess we are in.
