Bear in mind that the tie-breaker for the Champions League is based on head-to-head performance, first, not goal-difference...

In the mini-league for the three tied teams, the results put the teams as follows:
Galatasaray SK 4 2 1 1 6-6 0 7
Cristian FC 4 2 0 2 3-5 -2 6
FC Girondins 4 1 1 2 5-3 +2 4
...so that is why the teams were placed as they are and you unfortunately did not qualify.
