Your fans may be more fickle than most but out Chairmen have always been too!
You have to spend money to get out of these league. I can't think of too many clubs that have got promoted and survived without doing so. But that doesn't mean you should expect instantaneous success. It took QPR two seasons, so why should we expect different? On the subject of QPR, the main thing Sven was criticised for by our fans was the performances, even when we won. But QPR played shocking football all through the season last year. Every team they played looked better, but they kept winning. We were doing this too to an extent (until the Brum game), but it wasn't good enough for the anti-Sven brigade.
Regarding Sven, I think he is a good manager, but his financially demands are (I'm guessing) more than he is worth. But don't underestimate the appeal of Sven abroad, something that I'm sure the Thai Chairman had in mind when he hired him. He wasn't my choice to replace Sousa, but I still think it's a mistake to get rid at this stage.
Maybe it was a mistake but you still expect to be playing good football and winning games maybe not convincingly but comfortably. Just coz QPR did it doesnt mean you can do it
