I think we've been warped into buying mode constantly and feel youngsters will never step up to the plate, only Iheanacho and Boyata have been given a fair crack at the whip off the top of my head since the takeover. One took it but Boyata wouldnt get into the youth system these days, it's much improved.
Maffeo and Angelino have everything you want in a football player, desire and technical ability, the rest can be sculpted and learned. There's no reason why these 2 can't begin their intrigation this season and become regulars by next season.
