The Blues takeover doesn't really change the landscape much, the new owners have been in de facto charge for a long time, the spending power is still extremely limited.
My main concern with Rowett would be that he tends to play quite reactive football, it's pretty light on possession and actually taking the initiative in games, I don't think we're anything like set up for that. Maybe he'd be different with a much higher budget etc.
We were good at St Andrews in August but they looked very poor indeed, in all the times I've watched Blues since he's been there you can admire the organisation and getting much more out of the squad(s) than should be the case given the quality on offer, but they aren't very good to watch.
