I do think it's for the better for all 4 parties if Mourinho is moved on now.
Mourinho because I no longer think he'll get the backing from the club or the players we currently have.
The players because most of them seem to want to get rid of him.
The fans because most of us want to move on to a different style, both on and off the pitch.
The club because of how we're performing.
The question then becomes who could possibly take over and be a genuine quality manager for United?
I don't really think there is such a thing as a perfect fit out there, so a system to help us as a club move in a direction together would be the best, whether that comes from Woodward starting to see things through the eyes of the football world instead of the business world, we get a director of football or we get a group of football people to help set the long-term course for the club. I'm all for the tradition we've had of giving the manager the reigns to rule the club as he wants, but right now that tradition seems to be holding us back. If someone proves themselves to be a long-term leader and quality manager and cares about the longivety of the squad and clubs reputation then by all means I'll hope for them to get full control like managers in the past have largely had, but just for now, because it's so hard to see us get a manager who will fix our situation single-handedly, I'd like to see multiple football people involved to plan ahead, in case the next manager fails I'd like for that failure to at least amount to some sort of progress towards a goal. Whether it's squad-rebuilding towards a certain style or getting closer to implement a style more successfully.
I think the name I've read that makes me most optimistic of the managers out there, who are gettable, is Zidane.
I believe he's achieved a lot as a player & in his short managerial career to command respect out of any player joining the club. But whether going for him is smart or not depends on what direction the club wants to go into.
To me, despite supporting Mourinho and hoping that he'd be a success here and thinking that a good amount of this seasons failures comes down to us not backing him in the summer, I can't see him continuing as things are anyome. There is no gain in it if the squad is devided on their support to him, the board won't back him more and the fans have for the most part turned, all while results are far from acceptable.
I think he has done a decent job at getting some quality acquisitions to the squad, like Pogba, Zlatan, Lukaku, Bailly, Dalot, Fred & Matic.
It also helps my view of him that he seemingly has helped in the process of making Shaw someone we can hope ends up as a top left-back in the future instead of another "what could have been". And on top of that he has helped us get rid of a lot of players who were not of the standards needed at any top club.
I think keeping him on would be a continuation of improving the squad, but it would be a big negative for all the aforementioned parties at the club, and we ultimately need better than that.
