Atalanta is not Sparta Prag. So it will be a different game for Liverpool. Liverpool is currently in top form and highly motivated to secure a win in the competition to give its coach the best possible farewell present they can, after they got eliminated from FA cup. Although Atalanta has shown promise, their inconsistent performance may not be enough to overcome Liverpool's momentum, both at home and away. Regardless, Klopp is determined to lead Liverpool to victory in his final season with the team.
Yes, you are right, Atalanta is different from Sparta Prague, maybe Liverpool is able to put a lot of pressure on Sparta Prague because this club is not a strong club in the European League, it is different from Atalanta, which has better performance because it is in the Italian League. The difference in leagues certainly determines the strength of the club, I see Atalanta is different from Sparta Prague, therefore Atalanta will not let Liverpool score as many goals as they did when they beat Sparta Prague with a landslide score.
Even so, Atalanta is not the favorite in this match because we know that Liverpool's strength is very good this season, so there are more people who favor Liverpool and make Liverpool the favorite of bettors. There is no doubt for me about Liverpool's performance. Atalanta has to accept the fact that maybe their struggle is just reached the quarter-finals and it was absolutely impossible to get rid of Liverpool.
After Liverpool can get rid of Atalanta, we don't know who Liverpool will be against. I hope Liverpool and Leverkusen don't meet in the semifinals because if they meet in the semifinals it feels like it's not enough and it's like watching the final match because I want to see their performance in the final which will certainly be very exciting and tense because the two clubs have almost the same performance in all competitions.
