Where I come from (south east of Nigeria) we play Christmas football leagues where every sub-communities bring out at least 15 players for the competition.
I've been part of this very competition for over 10 years and as a committee member.
As a member of the committee, I invest as much as I can so as to encourage other people to take part in this football competition.
After that, we share at most 70% of the money invested in the competition to winners (first, second and third positions) and also use the remaining to sponsor their football careers.
