Who is already through to the knockout rounds?

Round of 16:

Liverpool are through and are guaranteed to finish first or second, and thus take a top seeding position in the bracket.

Barcelona have also secured a top-eight finish with a dramatic winner in a 5-4 comeback victory at Benfica.

Guaranteed at least a place in the knockout playoff round:

Atlético Madrid, Atalanta, Arsenal, Bayer Leverkusen, Internazionale, AC Milan, Feyenoord, Aston Villa, Brest, AS Monaco, Lille, Borussia Dortmund, Bayern Munich, Real Madrid, Juventus, Celtic

How it looks: the battle to go through

Before the competition began it was thought that 16 points would secure a place in the top eight, but the low spread of points at the bottom of the table means it could take 17 points to be absolutely certain of going through. It now looks possible to finish outside the top eight on goal difference with 16 points.
