Many people think both teams can make it to the final this season, but somehow I'm not sure Leverkusen will make it to the final. This is still the quarter-final stage and all teams will fight, even if Leverkusen can qualify for the semifinals then I am sure the competition will be even more difficult. I'm only optimistic about Liverpool's performance and chances in the Europa League, the rest is not.
Why do you doubt Leverkusen to be in the final round?
Although Leverkusen didn't play very impressive in the match against Qarabag, they finally eliminated Qarabag and keep the record of unbeaten in all competition during this season. Don't you think Leverkusen deserve to play against Liverpool in the final with this unbeaten record? In my own opinion, I even believe that Leverkusen deserve to win this competition. You can see the fact that Liverpool got 2 loses in the group stage but Leverkusen played perfectly with 100% win. So, it is quite strange if you don't trust Leverkusen to be in the final match.

Agree. It is very difficult not to put a team like Leverkusen in the final, they have been very consistent this season and have not even been beaten and Leverkusen have set new records in the Bundesliga and Europe. Indeed, in football anything can happen, especially in European competition, the team at the top can lose to the team below, but looking at Leverkusen's progress this season, it seems very difficult to stop them. When fighting against Qarabag, their struggle was very visible. They do not give up easily and continue to try as hard as they can until they achieve victory. So I hope Leverkusen progresses to the final.
Liverpool may score many goals but the performance of Liverpool didn't very impressive. If Liverpool plays against a team that has a strong defense, I'm not sure Liverpool can win it easily. We must be aware that Liverpool will play against Atalanta, it is one of the teams from Serie A (Italia league). They must be careful because a team from Serie A always has a great defense.
Liverpool's record against Serie A representative teams is quite good so there is no reason Liverpool cannot win this match. Liverpool will now try hard to win the Europa League and EPL League for Klopp's farewell.
