This is a bit of an issue.
We, like most people, want a reasonable guarantee of success.
But were not getting anyone from the top 6 teams and then most / all of the ones below are either past it / never been it / or massive gambles.
Therefore youre left with non PL appointments which are also gambles.
However given the current PL experience options its pretty much only possible to want a gamble.
What I think does need to be taken into account is that if someone does a good job for two seasons and then gets sacked in the third doesnt make that job a failure from the point of future considerations.
Looking for people with a track record of a number of 4/5 year successful stints is going to come up with a short list indeed (Guardiola...).
I think that is symptomatic of modern day football. In years gone by when players had to bust a gut to earn a living it was more common to stick with a manager as players didn't down tools so quickly and easily for fear of losing their income.
Today's pampered millionaires quickly lose the motivation to bust a gut for a manager and need a regular change of voice to keep them motivated. There's no shame in changing your manager every few years to keep it fresh as long as their is some continuity from above, Chelsea have been successful with it for example.
I think we'd be a perfect fit for aspiring, talented managers who have reached a certain level of success but aren't yet at the level of the top tier, but who could want to use us as a springboard for it. If we had a stable board and experienced DoF we could look to apply this model, but until we get that no manager with genuine aspirations will look at us as anything more than a cash cow.
