It's because they're trying in desperate vain to emulate Germany. What they don't understand is that Germany has a much more refined youth football system than England, and when they bring their youngsters to the senior team they're already hardened, experienced internationals who have won competitions at both U21 international and club level. What England is doing is grabbing a few youngsters because they can play some fancy football and trying to give them a "baptism by fire" approach by throwing them in the deep end. It's a backwards approach and unless the system is overhauled from the bottom up, England will continue to degenerate in the way we have been doing.
