Albion, Charlton and Chelsea among others actively scout youth football in Sussex. Anyone who is any good should get spotted well before the end of U16 football.
Although I do not agree entirely with you, there is an element of truth in as much as most boys playing at a good level in Sussex up until the age of U 16's would of likely been watched a number of times from scouts from different clubs.
Without an approach it offers a degree of opinion that maybe your seen as not having the potential for becoming a professional, but there are some quite outstanding exceptions.
Best to play football to enjoy and get better rather than to get scouted.
