Yes, Liverpool will be aiming to win the Europa League this season, winning it this season will be a good thing to put away disappointment of last season. Liverpool have a good opportunity to win the title this season since there are not much tough opponents competing in the Europa league that can match Liverpool’s strength except Klopp decides the Europa league will not be a do or die affair for them this season.
Yes, Liverpool is indeed one of the candidates for winning the European League this season. But it won't guarantee 100%. Because after all, the European League sometimes gives unexpected surprises. Not only that, several big clubs from other leagues are also in European this league. Maybe there will be some pretty tough competitors like Atalanta, AS Roma, Villarreal, Bayer Leverkusen and several other clubs. Even though in terms of experience, Liverpool should have its own advantages.
We all may feel optimistic about the strength that Liverpool has in the Europa League. But you are right that in every league, sometimes the final result is always unexpected. Even in the Champions League last season, we saw that many of the superior teams lost more quickly. So football has always been the most interesting sport. Because the results of a match and a league sometimes always surprise us all.
I personally feel that Liverpool will remain focused and prioritize the Premier League. But Liverpool will definitely fight to the max in the Europa League. I think it's time for Liverpool to win another title in one of the competitions.
