As Atalanta have qualified for the quarter finals of the Europa League, their performance is not so poor. Atalanta performed relatively well which allowed them to play against Liverpool in the quarter finals. Considering the current performance in the match between Atalanta and Liverpool, Liverpool must be put ahead. Liverpool will definitely be ahead and if no accident happens Liverpool will definitely win against this team and secure the semi-final. I am making this comment based on Liverpool's current performance. As they have been performing consistently in the Europa League and English Premier League, it will not be difficult for Liverpool to overcome the hurdle of the quarter finals.
Atalanta's performance in the UEL was relatively good because he was able to reach the quarter-finals and against an EPL team which was a big obstacle for Atalanta in this round, Liverpool is clearly superior in this match because Liverpool's performance is very strong this season and he will try hard so that there is no the team that stopped them from reaching the final. Liverpool will eliminate teams in every round somehow, Kloop is very ambitious to get the UEL trophy at the end of his time and that will happen if Liverpool continues to appear consistent and doesn't make any mistakes.
Because this is Klopp's last season, of course he will give everything in the Europa League competition to win the title so that his farewell to the team will be even sweeter at the end of the season.
Against Atalanta there shouldn't be any difficulties for Liverpool because if you look at it overall these two teams have different performances and Liverpool is much better than Atalanta.
However, that doesn't mean that Atalanta can be underestimated either, every team that has been in the quarter-finals is a strong team that has gone through a long process and Atalanta has succeeded in going through that process to finally be here.
Atalanta's performance is actually not as good as last season, in Serie A they were only able to achieve 1 win from their last 5 matches, this indicates that they are not doing well now and their ability to reach the quarter-finals of the Europa League this season is not always due to strength but motivation those who are high on different stages will reap different performance.
