Our fan base is the most gullible, easily manipulated and probably hero-worshiping one I have seen. The easiest way to become the savior of the fan base is to
1. Be a current player who never plays, even if you have shown time and again that you aren't good enough anyway e.g. VDB, Bailly
2. Be a former manager who was rightly fired for not meeting expectation e.g. Mourinho, LvG
No other fanbase rever their old regimes as much as ours do even in the face of overwhelming evidence that those old regimes might not have been the solution anyway. The last two champions leagues have been won by former PSG managers, but you never see their fans going crazy try to justify the results of those managers at their club, or blaming their sacking on the players, board, other fans etc.
Yet it happens everytime with us. Imagine if LvG or Jose won the champions league back to back, it would have been carnage on here.
Any way you dice it, Ralf failed here. He might have told you what you wanted to hear, but for the job he was hired for, he was an absolute failure. There were mitigating factors, but same logic could be applied to other managers, at other clubs too. I cannot take your opinion of RR seriously if all you need to support his famous 'recommendation' is "calling our the club and players", any idiot could do that. We would never know what players he recommended, or if they were good enough anyway.
And yes, if we needed someone to build the club, I'd much rather united poached DOFs/Technical directors from the likes of Brentford/Brighton, clubs who have grown mostly organically and done it in a competitive league like ours. For all the good PR Rangnick has managed to amass for himself, he was backed by the equivalent of a sugar daddy, buying their way through several divisions to the top of the German league. That does not impress me personally.
