I've was lucky enough to get a tour of Murray Park and it's a pretty impressive set-up in terms of the facilities it offers. I don't know much about our scouting or youth development "systems" as such, but certainly in terms of the on-site facilities it's all there.
As for whether its a training or youth development facility, the answer is definitely both. The facilities are designed to cater for the first team squad's every need in terms of their preparation & recovery AND to give our youngsters the best environment in which to develop. Both are said to be equally important to the Club.
It's an interesting approach they have to combining those two objectives, one that was apparently insisted upon by Dick Advocate at the design stage and copied from the Ajax system. There are areas of Murray Park that are used exclusively by the first team squad (e.g. certain training areas, players restaurant & lounge etc.) These areas are purposely high-spec and deliberately positioned within full view of the youth facilities, the idea being that the youngsters will see the first team squad every day and aspire to progress to their level.
An example of this is the changing complex, where there is a single corridor running from one end of the building to the other. At one end is the youngest youth team dressing-room, the next age-group up is the next door up and so on, right up to the first-team dressing-room at the top of corridor. Again, the idea is that the youngsters will see the first team as their ultimate goal and they'll work hard to progress year on year up the corridor until they reach the first-team dressing-room.
I'm no expert and I've really nothing to compare it against, but it looked to me like our players (old and young) are certainly very well provided for.
