Some of these clubs have 3-4 teams per age group x the number of affiliates they have so the potential pool of players could be in the hundreds. Let's face it some of the kids never get a look, not in the right geographic area, academy coach has some existing players they are trying to accommodate, existing regular coach(es) don't recommend their players or have any say in the matter, and several other reasons why despite the numbers the system is not open and it takes a bit of luck for some players to get involved in the da program.
