Considering how good they are in times of performance and comparing to other clubs on the Europa League they have the best performance and they are leading the Europa League table, perhaps just like you said this Europa league season is for the Liverpool because they have many points different from others so is actually obvious the trophy is for them.
They are still not quite where they used to be a few years ago. They were this team with Manchester City that nobody could really beat. But they are vulnerable, not as much as they were last season, but still they are losing important points in games that should be a win for them. The last of those games was against Luton Town.
In my opinion that if people are not right by judging the performance of liverpool against a low tier club in europa league to be compared with the result against luton last days.
Liverpool will obviously getting perfect result in europa league, probably win the league and qualify for UCL.
