Ferdinand, a product of West Ham's youth academy, said: "I think there is scope for more to come through. There are quite a few that are decent but the standard of the players that have come through has maybe slowed a little. That is because of the amount of money being spent on established players.
"A coach these days can't wait for a young player to develop because he can go out and spend £10million on the finished article, a player that can slot in straight away.
"The patience is not there like it used to be. I remember Harry Redknapp at West Ham putting me in and out of the team over the course of a year when I was young - just giving me a taste. You can't really do that any more.
"Hopefully, it won't discourage players because they can still see the likes of Wayne Rooney coming through.
"They may just have to wait until they are 19 or 20 to become regulars at their club."
