it depends on how many the coach needs or will accept. but you need 11 to start and then subs.
In a soccer match you can only have three,3, substitutes in a match.
11 plus subs 20 or for juniors 5 plus 3 subs
the sames as mens soccer. 11 on the field and 3-5 subs
11 players per team plus 3 subs
Up to 7 on the bench, 3 can come on
I think they have five subs on the bench,.
You need 11 at the least but 16 to have subs and everything
11 on the pitch. 5 Subs (3 can be used in a match)
it is the same in every year level, 11 on the field and however many subs there are
