My sons play in with a local team Tulse Hill Juniors. It's an old South London club that stopped for a while and is now rebuilding its squad.
They train on Saturdays (10am-12, opposite the cafe in Dulwich Park) and play matches in the Tantridge League on a Sunday morning (their home matches are played on the Dulwich Prep pitches)
The club really needs to find more players. Today for example although they fielded 3x teams, the U9s played with 1 less player than their opposition and had no subs.
It's a friendly club - both kids and watching parents.
They are also looking for anyone who would like to be part of their coaching team.
for more detail, or just come along on Saturday morning (stud boots, shin pads etc)
