I think a lot of it is that we've been starved of anything remotely resembling success for so long that the thought of fucking this brilliant opportunity up in true City style is scaring the absolute bejesus out of some City fans.
We're bringing in top players, being linked with yet more top players, and spending top wedge, yet we have a manager who is completely unproven at the level we're aiming for.
I think a lot of the 'Hughes Outers' simply want to play the percentage game; i.e. Who is more likely to get us where we want to go - Hiddink (etc etc) or Hughes?
It's the thought of us being the richest football club on Earth yet failing to win anything or even break the Top 4 because of loyalty to an as-yet unproven manager that is scaring a section of our fans, in my opinion. And who can blame them? I think we all have a bit of dread inside us that City could somehow fuck this wonderful opportunity up in our very own inimitable style.
So I guess I'm going for Option 3. We need to give ourselves the very best chance of succeeding, mainly because we can. I'm not sure we're currently doing that.
