Leverkusen once again proves to be a great team and at this point for me they are the favorites to win it all.
Yeah Liverpool and Leverkusen have taken places in the next round so actually this match did not have any impact on them but on the other hand Leverkusen does not give an opportunity to anyone who comes to their home will definitely be defeated, meanwhile Liverpool preferred to play safe they don't want to spend a lot of energy because lose or win does not have any impact on their position, as you said they would prioritize more important matches in the Premier League or in the next round they must be able to organize their schedule as best as possible.
This season it seems that the European League will be dominated by teams from the Premier League at least 3 teams are in a safe position to go to the next round West Ham, Liverpool and Brighton and I'm sure one of them will take a place in the final yeah maybe Liverpool. But what makes me wonder is why there is only one player from the Premier League who is on the top scorer list? I didn't see West Ham and Liverpool players there even though we know that in the Premier League there are Jarrod Bowen from West Ham and Mo Salah from Liverpool who are in the top 3 top scorers.
