I guess there's no easy way to do this, but just to throw out another opinion, maybe it would be best for the premier league teams to have "decision days" before the other clubs in the age group. I do realize that this could bring up a whole other set of issues, but it seems like tryouts should be held first for the teams who have the most players that would rather play for that team before any other one. (and PL teams are in very high demand).
