The future manager?

Hi all, well with the expected arrival of villas-boas to chelsea I got thinking. At only 33 years old he's extremely young to be the manager of a team like chelsea which is obviously a very demanding high pressure job. However, what's most unique about him is that he wasn't a football player in his younger years and seemingly just entered into coaching. Correct me if im wrong, but isn't jose mourinho very similar in that he too played very little or no professional football and just entered coaching directly at young age. Both have been relatively successful and probably more successful than other managers their age who started life as footballers and who made the natural transition into coaching (mourinho obviously moreso than villas-boas).
Basically, I was wandering do you think in the future will we see more of this type of manager rather than the current system of retired players moving into coaching. Do you think in the future we might have almost an academy system for managers, whereby a club may take a highly promising 24 year old and almost train them into becoming good managers that are tactically astute and who have an eye for talent, grooming them with the hope that 15 years down the line they'll be primed to take the managerial spot. I'm not saying this'll ever happen on a mass-scale but do you think any team will ever give it a go?
