Competition format
The six teams are drawn into two groups of three teams. Each team plays the other teams in their group once, earning 2 points for a win and 1 for a draw. The two group winners advance to the final. If the final is a draw, a penalty shoot-out is used to decide the winner; there is no extra time played.
