Each match lasted 80 minutes, consisting of two periods of 40 minutes, with an interval of 15 minutes.[2]
Participating teams
One team from each continental confederation participated in each tournament.[3][4] The same country may not participate in both the boys' and girls' tournament. As hosts, China was given Asia's spot to compete in the girls' tournament (and thus could not participate in the boys' tournament). Teams may qualify through preliminary competitions, or be nominated for participation by their confederation, with the invited teams ratified by FIFA during their meeting in Zürich on 3–4 October 2013.
