Please Help qualification's Match

Hello, i have a problem with qualification my team ist normally in the next round because i have 9pts and the 2nd has 9pts too but i have+1 and he has 0, we have both 9 goals! but he is actually second and im third, any help please before the next championsleague match starts pleasE?

If points are the same I thought it was away goals as tie breaker, but it could also be Head to Head. You are not the only confused person.
