During the last season, Liverpool performed well and even came very close to winning a champions league ticket for the next season, but in the end, they didn't have the potential to win that ticket and they lost it to Newcastle United. As Liverpool is currently in good form, I think it is possible for them to be an excellent candidate for the Europa League next year.
Oh, I wouldn't talk about Liverpool's excellent form right now, because the previous season is over and a new season is about to begin with rivals who will already look different, however, like Liverpool itself. As for the ambitions to get into the Europa League next season, I think that Jurgen Klopp is still counting on the Champions League 
Although, of course, it's too early to make predictions when the season hasn't started yet.Until now in this winter transfer window, Liverpool recruited two attacking midfielders. Firmino who left them for free to join Al Ahli in Saudi Arabia league, left his spot to Darwin Nunez only, who should improve more and more to boost the team scoring ability. Mohamed Salah is the only right winger too but there is Gakpo who could play in this position too. I find the attacking line quite limited along with the number of players in Liverpool comparing to other teams.
