Champions League permutations: Who needs what to reach the last 16?

Six teams have already sealed their place in the last 16 with two games to spare, and nine more clubs have the chance to join them in the draw over the coming days.

Some of Europe's biggest names still have work to do to ensure that they will be in the hat at the turn of the year, while even in the groups where the top two has already been confirmed, there are things to fight for such as top spot and third place.

Here, Sports Mole rounds up all of the permutations ahead of Tuesday's and Wednesday's fixtures.
