Knockout performance: round of 16 form guide

Paris Saint-Germain and Benfica are the only sides in this season's edition who have not lost a UEFA Champions League round of 16 tie in the competition's current incarnation.

While Barcelona (nine successive aggregate wins) and Real Madrid (six) are both on a roll, Arsenal have lost their last six ties at this stage. Bayer Leverkusen, Sevilla and Napoli are looking to break knockout stage ducks when the action resumes.
