May I know what is the Champions League Group Standing Rules.

I am currently position no.2 with 9 points Gf=11 Ga=8
Last CL match will play against no.3 with 6 points Gf=10 Ga=9

So for our last match, as long as I lost 1 goal, no matter 0-1, 1-2, 2-3, 3-4, both 2 teams will have same points, same goal difference, Gf and Ga.

I checked Rules & Prizes but do not have any description on group standing rules.

Which team will advanced to final 16?

Ps: I win 3-0 on first round.

Sorry my poor English.
