Explanation (from wiki):

In the draw for the round of 32, the twelve group winners and the four third-placed teams from the Champions League group stage with the better group records are seeded, and the twelve group runners-up and the other four third-placed teams from the Champions League group stage are unseeded. The seeded teams are drawn against the unseeded teams, with the seeded teams hosting the second leg. Teams from the same group or the same association cannot be drawn against each other.

So basically we can play with everyone from the seeded group except Tottenham and Fenerbahçe.

The draw will be held on 12th of December 2016
