On 22 May 2013, the draw for clubs to participate in the tournament was released.[3] Due to dropouts the fixtures and group draws were amended only on 15 July, three days before the tournament.[4]
The group stage featured eleven teams, with 4 teams in Group A and B and only three in Group C. Three teams advanced from Group A and B and two from Group C.
If two or more teams are equal on points on completion of the group matches, the following criteria are applied to determine the rankings (in descending order):
Number of points obtained in games between the teams involved;
Goal difference in games between the teams involved;
Goals scored in games between the teams involved;
Away goals scored in games between the teams involved;
In the knockout stage, teams play against each other once. The losers of the semi-finals played against each other in a third place playoff where the winner was placed third overall in the entire competition.
