As the title says. I'm helping out at an u16 team and basically it sounds like the amount of players who are turning up can be really hit and miss. Alot of what I look at requires a certain number and aren't always easy to adjust if alot more or less turn up. I have a few basic ideas such as a keep possession type session or a attack vs defence one where I could use 2 goals if needed but wondered if anyone had something they had used before.
