With this Liverpool's current form, we expect them to be one of the best and strongest teams in the Europa League next season, but seriously, nobody can actually predict how Liverpool's performance will be because other teams may also build strong teams next season, and seriously, this is no what we expected from Liverpool's performances this season. But still, Liverpool can win the Europa League because, even though they had a bad season, they always performed well in other competitions.
This season Liverpool are favorites in the Europa League but we cannot say that Liverpool will win the Europa League. Last season did not go very well for Liverpool. If they perform this season like last season they will not do well in the Europa League. As the season is new, they should perform consistently from the beginning of the season. Because performing poorly throughout the season and then performing well at the end doesn't help that performance. By spending some money in this summer's transfer market, they can bring in a few players to make it easier for Liverpool to build a strong squad.
