The second legs of Champions League matchups are often where the magic happens and where the drama manifests. The opening 90 minutes set the table for what's to come, and that means either the desperation of a comeback attempt or the intensity and tension of a potential upset.
This season's round of 16 is no different, and with the removal of the away goals rule making things more mathematically straightforward and a number of ties still hanging in the balance, the next couple of weeks should feature some memorable moments.
Half of the eight series are level after the first leg, with another currently a one-goal margin.
