How many youth soccer players are allowed on the field at one time?

Question

I have been recruited to coach 12U team this fall, not that I mind it, just need a little guidance on the fundamental of the sport. I also did it so I can spend more time with my son ( who happens to be on my team) I want to be a good coach and guide these guys, I don't want to add any confusion.

Answer 1

11 players including the goalkeeper are allowed to play in the field

you can have more like 6 or so incase one gets injured then he will swap with the injured player
