Let's assume that two teams need to compare:
A has been qualified; B/C comparison (only those with the same integral are eligible for comparison); D out; Compare according to the following rules:
1. Goal difference (3 rounds of "total goals scored-total goals conceded"), if it is the same, turn 2;
2. The number of goals (comparison of the total number of goals in three rounds), if it is the same, go to 3;
3. Mutual score (in the comparison between the two teams, the winner goes out and the loser goes out; A draw is a draw, because a draw means that the goal difference is the same.
4. Record the target differences with each other (no comparison is needed)
5. The number of goals scored by each other (no need to compare)
1, the second step is easier. When the three teams need to compare, when the second step is satisfied, start the comparison from the third step.
Suppose three teams need to compare:
A has been qualified; B/C/D comparison (only those with the same integral are eligible for comparison); Compare according to the following rules:
1. goal difference (3 rounds of "total goals-total score")
①B& gt； c，D； B is out, C and D are out;
②(B =(C/D))& gt； (D/C), the same players are compared from 2 according to the situation of 2 teams; The little one came out;
③ B=C=D, and go to the following 2 steps;
2. Number of goals (comparison of total goals in three rounds)
①B& gt； c，D； B is out, C and D are out;
②(B =(C/D))& gt； (D/C), the same players are compared from three according to the situation of two teams; The little one came out;
(3) b = c = d, and carry out the following three steps; 、
3. Record points with each other (comparison between the three teams)
Compare the games of B-C, B-D and C-D, and the total points of each team.
①B& gt； c，D； B is out, C and D are out;
②(B =(C/D))& gt； (D/C), the same players are compared from three teams according to the situation of two teams; The little one came out;
③ B=C=D(B wins C, C wins D, D wins B/ Quanping), and go to the following 4 steps;
4. Record target differences with each other
Compare the B-C, B-D and C-D matches between the three teams (total number of goals-total number of goals conceded).
①B& gt； c，D； B is out, C and D are out;
②(B =(C/D))& gt； (D/C), also go to the following five steps to start the comparison; The little one came out;
③ B=C=D(B wins C, C wins D, D wins B/ Quanping), and go to the following 5 steps;
5. The number of goals recorded by each other
① There are only two teams left (B/C)
Winner out, loser out; Pingze draws lots to decide promotion;
② There are 3 teams left (B/C/D)
Compare B-C, B-D and C-D, among the three teams (total goals).
If b > C/D, b out, C/D out;
if(b =(c/d))>； (D/C), b and C/D draw lots to decide to qualify; Dc output
If B=C=D, then team 3 draws lots to decide who will qualify;
Of course, this is a situation where the team is relatively small. If there are many teams in the group, it is easy to draw lots to qualify. If you are interested, you can infer that 4 or more teams compete for one or more places!
