I am not too fond of writing observational posts, but as a general football observer and an English football enthusiast I think I would share my thought. Not claiming it is original though
As much as Manchester United supporters hate Liverpool, and vice versa, I think these two football clubs are more similar than their supporters would like to admit. They closely resemble in terms of the City, support, success, failure and tragedies. I remember seeing a fantastic video on the rivalry of these two great clubs two or three years ago. It was very apparent to me that how these two cities and their most successful football clubs tend to follow each other cyclically.
What Manchester United is going through is identical in many ways to how Liverpool was drifting away for 25 years. Of course your owners are the biggest reason for this mess, and their ineptitude was hidden by the greatest club football manager for some years, but I think SAF and his legacy is creating an hindrance for the club's path forward. Although RedCafe is not the ultimate indicator of Manchester United's local and match going supporter base, it is still an indicator nonetheless. I have been following RedCafe since 2018, and every-time something goes wrong on the football side, I see a thread about how Sir Alex would have done it or how his football identity needs to be brought back and how Ole will reinstate SAF's method.
Unfortunately, this is the same nostalgia Liverpool supporters showed in the early 2010s, reminiscing how great Liverpool was under Paisley or Dalglish. There was a huge support and uproar of delusion from Liverpool fans when Dalglish was reappointed, when every unbiased football fan could see that he was out of touch with modern football for a long time. Only since Klopp, the club's general support has realized that though history, especially the history of success is important, but there is a time to let it go and not affect your current progress. I think the same needs to be realized by United fans. Let your new manager and players write their own history instead of burdening them with the earlier one. Even with your current sticky situation, I am confident that with two or three correct appointments Manchester United will bounce back to the top (Probably not as dominating as earlier due to the Nouveau Riche clubs) due to its resources.
My other observation is regarding the effectiveness of your supporters groups. Here, I am afraid, you are lagging behind Liverpool supporters groups. I remember that Spirit of Shankly's constant effort played an important part in removing Hicks and Gillett from Liverpool's ownership. FSG has saved Liverpool in a way, but they are greedy cnuts and not ideal owners. With the ticket price raise, the furlough debacle during covid, the super league mess, etc., they have done a lot of things wrong. But every time they backtracked due to staunch opposition from the supporter's group. Granted your supporters group have vehemently protested the super league idea, but the only other time you have rebelled against Glazers was during last year's game postponement , which did not give a good impression to the neutrals and in hindsight, halted your team's momentum. I think in this area United supporters need to look hard at themselves.
Anyway, I am probably dithering, and also feel like this is probably not the right thread to post my feelings. Please accept my apology. As a football fan, I would love to see United back competing at the very top. All the best
