Real Madrid are already through in Group F and, at the moment, it's just as well.
That's because the Spanish champions are already 2-0 down in Leipzig.
RB Leipzig, who could qualify with a win tonight, led through Josko Gvardiol's 13th-minute header and double the advantage when Christopher Nkunku smashes a stonking strike in off the bar.
In Group E, Benfica and Paris St-Germain will be both assured of their spots in the last 16 with victories.
Benfica are 1-0 ahead against Juventus, while Lionel Messi has just stuck PSG ahead with a nonchalant touch from the outside of his left boot.
