In the first stage, every team had to play against every other team of their group (
round-robin). This meant five matches per team. From every group, the three best teams advanced to the second stage and the three worst teams were eliminated. In the second stage, two new groups were formed. The three best teams from groups A and B were united to form group E and the three best teams from groups C and D were united to form group F. In these two new groups of the second stage only matches by teams that had not yet played each other have to be played. As for the matches that had already happened in the first stage, their results also counted in the second stage. Therefore, every team played three matches and there are 12 teams in the second stage. Out of the second stage, the four best teams from each of the two groups advanced to the quarterfinals (8 teams in total) whereas the two worst teams will be eliminated from the championship (four teams in total). ==Financing==
