Could anyone explain me why my team, FC Girondins, is ranked 3rd and not qualified ???

3 teams are in the battle : Galatasaray SK, Cristian FC and FC Girondins, all with 10 points after 6 matches.

Results :
FC Girondins - Cristian FC : 0-1
FC Girondins - Galatasaray SK: 1-1
Galatasaray SK - FC Girondins : 0-4
Cristian FC - FC Girondins : 1-0

Cristian FC - Galatasaray SK : 0-2
Galatasaray SK - Crisitan FC : 3-1

Ranking:
1 - Galatasaray SK - 10 pts - BP 9 / BP 8 -> GA = +1
2 - Cristian FC - 10 pts - BP 5 / BC 6 -> GA = -1
3 - FC Girondins - 10 pts - BP 9 / BC 4 -> GA = +5
