By their own admission, Liverpool weren't at their best in their victory over Inter Milan on Wednesday night.
Andy Robertson suggested he and his teammates were "sloppy with the ball," with Inter on top for periods at the San Siro before the introduction of a number of substitutes swung the tie in the Reds' favour as Roberto Firmino and Mohamed Salah found the net.
There were moments in the game when Simone Inzaghi's hosts looked the most likely to open the scoring, but they have instead been left with an uphill battle just to stay in the Champions League.
