Dunno - as many as it takes for the clubs and FA to start agreeing I suppose...? Sounds like they're more or less there, the age-appropriate modules are very good and mandatory relsease would be a massive step.
One of the plans is to introduce 9v9 for u11 through to u13 football which includes an intermediate pitch and goals between mini and youth soccer. This includes smaller goals and pitches rather than the current huge leap when players move from 7 to 11 a side. Problem is though is where will the money come from for youth clubs, many of whom are voluntary organisations who rely on grants and parents support to keep running.
As of yet neither as a club secretary or someone who is on the Sussex Sunday youth League committe, no one knows.
