That silly result certainly won't be "largely forgotten" anytime soon no matter how hard you're hoping for that to happen
A trophy is always nice and so is qualification for the Champions League, but
it's not like you're in with a shot, so it only counts for so much. Of course still much better than the Europa League but we've been in the CL for 5 or 6 years in a row under Klopp I believe (or have we been out one year as well, not sure), so it was bound to happen sooner or later once we had a down year.
