You have many, many problems:
Your owners (relatively minor - apart from letting Old Trafford go to pot, that's unforgivable - and the fact Woodward has seemingly not had to answer to them yet). People are upset because they seem to be business minded as opposed to focused on winning - that's the vast majority of people that own football clubs. Not something to justifiably moan about.
Woodward (pretty major - although I'd argue he has been unlucky in some respects). People criticise Woodward for being unwilling to sack managers until being in the top 4 is mathematically impossible - I think it's noble and fair.
However, too many bad decisions, too many poor transfers in and out effectively sanctioned. Letting Herrera go on a free. It will not do.
Ole (major) - he has left the squad threadbare, even if he has clearly got rid players who are either not good enough or never wanted to be there. However, the football played is painful irrespective of results. That's simply not good enough. Good transfers though. People say they were obvious, but most of your 'obvious' transfers pre-Ole were a disaster. Therefore, Ole gets the kudos for it. And to a lesser extent, Ed. But the football, good grief. I do not think he can sort it, but I also think trying to save a season is an absolute mug's game. Managers and teams can be streaky. A good streak may well be coming when players return from injury. The football will still be poor though unless Ole changes some things drastically.
Fans (pretty major): You essentially pushed Mourinho out, and Ole in. Nice going. You also refuse to adjust expectations on the basis that "We are Manchester United". Any fan who has used that phrase as a 'reason' you should be doing better fully deserves what you are getting right now.
But I digress...without a doubt the club should not be swayed by fans, especially regarding hirings - that's pathetic. But if you hired someone else, and they underachieved, it's guaranteed that a very large amount of fans would be on Woodward's case for not giving Ole the job.
Also, because Molde's season was about to start, Woodward had to make a call on Ole there and then - he could not wait until the end of the English season.
Of course, he made the wrong call, which is typical of him.
