Grading: 32 teams are divided into 4 grades, with 8 teams in each grade. The grading is determined according to the team's European club football ranking (UEFA club ranking). The top 8 teams are in the first file, the teams ranked 9- 16 are in the second file, and so on. Same country restriction: teams from the same country cannot be divided into the same group when drawing lots for group matches. This can ensure that the opponents in the group match come from different countries and increase the diversity and appreciation of the game.
Grade balance: Each team must include teams from different grades. This can ensure that the opponents in the group stage are equal in strength and increase the competitiveness and fairness of the competition. Position balance: In the group stage, each team will play home and away games with the other three teams. This lottery grading rule is to ensure fairness and justice, and prevent teams from the same country from playing home or away games at the same time in the same round.
