There's a lot of academies like that around the world, Glenn Hoddle even has one.
I think the idea for Scotland would also work, but they exist here as well. There's a football academy/school thing right next door to me, in fact lol
Usage is different I think, they're probably more or less used as "feeder" academies...
Super Kevin Campbell runs one too. His is a business enterprise, send YouTube clips in of your kid etc and if they're deemed good enough you pay to be at his academy and the academy promotes the kids to clubs.
