You are right and I agree with your opinion that the term "epic comeback" will be a new hope for Liverpool to turn things around, even though it is a little impossible because Liverpool have to play away from home, but we all know how Liverpool's players will look if they play at full strength, Liverpool are even able to create big aggregate and without conceding a goal, who knows, there is still a glimmer of hope for Liverpool to score lots of goals at home to their opponents later and Liverpool not conceding a goal so Liverpool still has the chance to qualify for the semifinals. Nothing is impossible if luck is on Liverpool's side in the second leg.
Even Liverpool's own performance in the Premier League was affected by their previous defeat in the Europa League. If Liverpool is able to regain their confidence again, believe me, Liverpool can become a scary club in knocking out their opponents. Currently, Liverpool is in need of motivation and support from fans to achieve their success in the Premier League and also European League if they believe, perhaps Liverpool will regain the confidence to beat their rivals.
Haha, yup, all of us know about a words,
"Impossible is nothing!", and in football we often see this moment happen. We will see both will play for 90 minutes, this is very possible for Liverpool to change the results. even only with 45 minutes, results can change quickly. Let's just say Liverpool went to Italy with an impossible mission, but I believe Liverpool will not play without confidence, they will trying to scored goal before Atalanta. Maybe, if Atalanta manages to add 1 more goal in this match, before Liverpool, that's condition will become the real mission impossible for Liverpool, since the match will become even tougher, and at that time I will start to think the Reds, who are one of the candidates to win the UEL, should go home.
