You need to be registered and have paid in order to trial. Trials are only for players who wish to be graded into the stronger divisions (the red or white teams for U/10 and U/11, or the Division 1 or 2 teams for U/12 to U/15). Trials for U/16, U/17 and U/18 teams are generally not held as players are assessed at pre-season training. Players in these age groups who wish to trial for Premier League teams can do so with a Premier League club of their choosing.
For the U12, U13 and U15 age groups trials were held on Thursday 7th March and Thursday 14th March (this later date was a replacement for Thursday 28th Feb which had to be cancelled due to rain).
