Generally I would say not to bother with staff that much in the lower leagues because you'll be sacking them before long, having 2 good scouts and a good assistant manager is all I really aim for with my staff.
The only good staff I've been able to get to come to me is Robert Prosinecki.
I've not bothered to find a good one yet, just sticking with my default. I normally wait until I'm in the second to top league until I buy any staff whatsoever.
