A simple solution would be that every year a player trains with you accumulates a fixed sell-on to any contract should they leave.
So someone signs for the youth team aged 12 and is picked up by Chelsea at 16 has a 40% sell-on built into their contract on top of the normal remuneration owed.
That would guarantee genuine talent creation would be rewarded.
