The competition system is similar to the Scottish Cup, which adopts the system of lottery, single competition and elimination by turns. In the first round, the 28 teams with the lowest ranking in the league last season drew lots to decide the game. The winning team of 14 advanced to the second round, and joined the team of 10 who ranked highest last season but did not qualify for the second round of Europe. The 12 team ranked higher last season was the seed team, and the 65438+ team won at home. Then join four teams to participate in the Euro *** 16 for the third round draw. Last season, the top eight teams were seeded, and the winning team of the eight teams advanced to the fourth round. There was no seed in the fourth round of lottery, and the winning team of four teams advanced to the semi-finals. Lottery tickets also have no seeds. The date and place (neutral stadium) will be selected by the management committee, and the winning team will advance to the fourth round.
