Our Champions League scenario

I just wanted to clear this up since there seems to be a misunderstanding of what it will take for us to advance. First off, our destiny is basically in our own hands. If we win out, we advance, it's (almost) that simple.

The only way we don't advance by winning out is if Marseilles has a greater goal differential in the overall group and we beat the French side by the exact score of 1-0. For that to matter though, l'OM will have to beat Beşiktaş by at least ten goals, given we defeat Porto by only a goal. The reason the fourth tie-breaker of group goal differential would come into play is because we both would have beaten each other on opposing grounds by the score of 1-0, thus eliminating the head-to-head and away goals tie-breakers.

Get it? Got it? Good.
