We barely bring youth through but the main issue there is we don't have good enough youth to come through for the PL as a whole. Whether that is a training thing, a problem with initial recruitment or even a self-fulfilling legacy that the better youth don't come to Villa as they know we don't promote much from within.
I can name two players in this millenia who have been at the top of the game after coming through our youth then leaving us and that is Grealish and Cahil. I suppose Barry as well although he wasn't initially with us and we thought Standing would be better and needed someone to help him settle. Jacob Ramsey might be another although he has dropped back since. I think we only have three graduates playing in the Prem league for other teams as of now although I stand to be corrected.
Hopefully a legacy of Emery is that we start training them better or better youth players start coming to us as a regular top 6 side and we see some more come through, but unfortunately I doubt it.
