Honestly , Leverkusen is playing so smooth that I wouldn't be surprise to see them in the finals or even winning it because right now they seem to be one of the first candidates alongside Liverpool to win the trophy this year.
It would be great if we could see the final between Bayern Leverkusen vs Liverpool, right? I know it's still too early because when enter the knockout round everything can change a lot, and in that round teams can't make mistakes that could result in them being eliminated, but if the two favorite teams continue to perform well then this will be an ideal final and very interesting to watch, but I still favor Liverpool to win the European League this season, maybe the feel not the same when winning the champions league but at least it's better because ending the season without a title is very unpleasant.
I think it's very possible to see Leverkusen at the finals because firstly Leverkusen is doing so well in their domestic league and they don't have another league they are playing at the moment except for the Europa and their Herman bundesliga so they have enough time to rest and always come back to give their nest moreover they are in a group where they happen to stand out so well so for now I'm very certain they will make it to the knockout stage.
Liverpool is also doing well so far but they are participating in too many competitions already such as the UCL, EPL, Carabao cup and the Europa so they may be likely fatigue and injury prone at some point and may not be at their very best in some of the games and may u see perform but then I'm very sure they could possibly make it to the knock out stage as their group is not that rough as well.
But then I think this is one of the leagues Liverpool can be sure to win if they dedicate much to playing better although they also have a chance with the UCL but the chances are higher here if the put in more efforts and focus.
