Goalless after the first leg, the equation is simple for Jurgen Klopp tonight.
Liverpool must beat German outfit Augsburg if they are to reach the last 16 of the Europa League.
Crucially, if Augsburg score at Anfield and the match finishes in a draw after 90 minutes, the Bundesliga outfit would progress on the away goals rule.
Moreover, if, for example, the match ends 0-0 in regulation time and then 1-1 in extra time, Augsburg would again progress on away goals.
Reds fans, however, will be hoping to avoid all those headaches, believing their side has more than enough about them to see off Augsburg, who are 13th in the German top flight, and who arrive on Merseyside with just one win in their last six games.
That win, though, came last weekend at Hannover as Augsburg recorded a 0-1 victory on the road.
Daniel Sturridge looks set to feature against Augsburg, but Liverpool will be without injured quartet Dejan Lovren, Adam Lallana, Martin Skrtel and Joe Allen.
Augsburg have injury problems of their own for the trip to Merseyside, with main striker Raul Bobadilla struggling with a thigh problem and central midfielder Markus Feulner ruled out with a fractured cheekbone.
Predicted Liverpool XI: Mignolet, Clyne, Toure, Sakho, Moreno, Henderson, Can, Milner, Firmino, Coutinho, Sturridge
Predicted Augsburg XI: Hitz, Verhaegh, Klavan, Janker, Stafylidis, Dong-Won Ji, Kohr, Esswein, Werner, Altintop, Finnbogason
