In sporting terminology, a youth system is a youth investment program within a particular team or league, which develops and nurtures (bringing) young talent in farm teams, with the vision of using them in the first team in the future if they show enough promise and potential, and to fill up squad numbers in some teams with small budgets. In contrast to most professional sports in the United States where the high school and collegiate system is responsible for developing young sports people, most football and basketball clubs, especially in Europe and Latin America, take responsibility for developing their own players of the future.
