Liverpool is one the top clubs and it is their duty to be good, since they are one of the top clubs the up and coming ones are looking up to, they played well in the just concluded season, atleast, ending the session in the fifth position is not an easy feet, but yet they did it, though i can not hide the fact that I expected better from them, but then like you said, a bad season always happens in one way or the other, even to top clubs, because that is all that there is about sports, I bet everyone would agree with me that the game would become super boring if it becomes just one club winning in every season.
I think Liverpool made quite a significant comeback in the season that has finished because they struggled to reach 5th place but finally kloop was able to do it. Even though some think that Liverpool have not been good enough last season, I admit that they have tried their best. Indeed, Liverpool must start a new era after the departure of several of their star players so they need time to find a good strategy that can be understood by every player. Salah, Gakpo and Nunez would have been an underrated trio last season but I think they will be highly reckoned for next season.
Apart from failing to return to the Champions League this season, of course, the weakness in team depth will be corrected by kloop in this season's transfer window. Firmino has also left I think Liverpool need a better stock of forwards for next season.
