Four clubs have already booked their place in the quarter-finals of this year's Champions League.
They are: Manchester United, Ajax, FC Porto and Tottenham Hotspur.
United pulled off one of the most remarkable comebacks in the competition, fighting back from a 2-0 home deficit, to win 3-1 at Paris Saint-Germain on Wednesday night.
Ajax also qualified despite losing 2-1 in Amsterdam, following their impressive 4-1 victory at Real Madrid.
Tottenham Hotspur claimed a 4-0 aggregate win over Borussia Dortmund and FC Porto needed extra time to see off Roma yesterday.
The other four teams will be decided next week.
Liverpool travel to Bayern Munich following a 0-0 draw at Anfield in the first leg. Manchester City have the advantage after beating Schalke 3-2 in Germany.
Atletico Madrid are away to Juventus, who they beat 2-0 at the Wanda Metropolitano, while Barcelona must overcome Lyon after a 0-0 draw in France.
