I do not think this is true. Whilst I cant speak on anyone's behalf - Mourinho is fundamentally appreciated by certain fans because he is a winner. He is widely regarded as a short term option who with him brings trophies & will do things and win things in any way possible; irrespective of the core substance & style that revolves around our club.
Whilst it may look like the best option to get us back to the top; some fans- like me, feel that this is just a stopgap option of momentarily instigating our dominance. The fan of this is what to me is a consumer - someone who may enjoy the benefits of a short term win over a more longer term plan & dominance.
I personally don't like fans calling other fans consumers - we are ultimately of varying beliefs of how the club should be run but fans never the less. Jose unfortunately cannot afford another year like this year- where the fans who wanted a quick & short term win in their books are likely to be much less forgiving.
Nevertheless- he is the current manager & many support the manager due to their affection of the club; we need not be head over heels about him.
Not everyone is just a consumer - some for example like me believe:
- The PL is likely to get harder & harder that eventually we need a different plan
- Money purely wont get us and keep us at the top; clubs are capable of spending to similar amounts if not more freely
- We need to build a brand of football & able to play that week in week out so that opposition play re-actively rather than pro-actively ( Under Jose we have been the team that has played way to re-actively/ changing formation/tactics to respect the opposition & have minimal practise of our game plan)
- Our youth system has some good players coming through; it would be a shame for many to not be given the chance like how Ibrahimovic replaced rashford leading to lukaku replacing rashford leading to rashford trying to shoot like Ronaldo.
- This is a pure personal opinion but I feel that a United approach is required to reach and stay at the top for the long term. We need a manager that understands what the fans want, what playing for United represents, how football should be played when wearing our shirts, someone who has United intertwined within their DNA - doing so may mellow the fans expectations for instant glory & allow a chance for a manager to grow in to a role where they can be here for a good 10+years. To me- football has been open to self created managers within the last 6 years & success has followed in a respectable manner.
Ultimately- Just because fans are not head over heels about Jose does not mean that they are not fans of United through thick & thin- because they are; just ultimately seeing a short term option struggle is like waiting for an apple to fall off the tree.
Fans appreciate Jose because he is a winner, and it is not easy to be a winner! It is far more easier to play nice and not win anything. I do not agree with this notion that Jose is short term option and only sees to improve the team in short team. Look at madrid, he setup a good team there. Their 3 champions league came with the players and setup Jose build there. The Chelsea team he built at his first stint ruled PL for a long time. Jose might not be the best in grooming youngsters, but he certainly looks to build for long time and he gives chances to the youngsters if the youngsters show that they can be reliable and can deliver what Jose wants. e.g., He gave good chance to Zouma in his second spell at Chelsea.
Many fans have exaggerated this notion that we always look to attack. These are the fans who think we existed after 2007/08. United have a long history , and we were good attacking side sometimes, but not so much attacking at other times.
These fans also want to throw wingers and cross the ball. That is outdated football, and hence why we dint win much in european football despite having resources to be a continental powerhouse and a very successful long term manager who had time and backing for 'long term planning'.
Many people believe that we need to look to build for long term rather than looking for short term, but that is just bullshit. You cannot build a good long term future if you cannot have a decent present. For e.g., if we had not bought Zlatan, then there will be lot of pressure on Rashford, maybe we wouldnt have won league cup, maybe we could have been knocked out of EL and missed on CL. Without CL, we might not have attracted Matic, De Gea might have pushed for a move, etc. Building for the long term while ignoring present is just bullshit and an excuse for current failures. The reality is if you cannot build a good current side, your best players want to leave, and the top players will never come, hence the puzzle will never be completely solved.
When we bought Shaw, that was deemed long term solution for LB, we all know how that turned out.
When was the last time we played homegrown younsgter as our striker? Its easy to say Jose does not give proper chances but I struggle to see any of our youngster making it in forward position during SAF era too.
You talked about our core ethos - let me tell you we have always been a buying club. We bought striker after striker and always ignored our youngsters. We bought Tevez, Owen, Berbatov instead of giving chance to our youngsters, that too when we were winning titles. So, I do not see any problem in Jose bringing Lukaku who is himself fairly young and learning and not just depending on goal shy speedster Rashford.
