The field is set. It's time for the real fun to begin in the Champions League.
The group stage came to an end Wednesday, with Atalanta and Atletico Madrid securing the last two available spots in the knockout stage of the competition. Here's a look at the seeding ahead of Monday's last-16 draw, which has the potential to offer up some truly explosive contests.
Teams from the same league can't be drawn against one another in the round of 16. The same goes for clubs that clashed in the group stage; Paris Saint-Germain can't meet Real Madrid just yet, for example, after they did battle in Group A. Those stipulations are removed for the quarterfinals.
As a result, the 16 teams still alive all have an idea of their prospective encounters. Reigning champions Liverpool, for instance, are guaranteed to draw one of Real Madrid, Atalanta, Atletico Madrid, Borussia Dortmund, or Lyon.
The knockout stage is slated to begin Feb. 18.
