They want this title but a next season will not be easy for them, firstly with one more age for Mohamed Salah and it has risk of declining performances from Mohamed Salah; and secondly the growth of PSG and Barcelona, recovery of Real Madrid and perhaps Manchester City. There will be more strong competitors in UEFA Champions League next season and Liverpool will not easily go to even semi finals or final match.
In many recent years, their attacking system and goal scoring task belong mainly to Mohamed Salah and a next season possibly is a transitional season of eliminate their dependence on this player.
If you look at the number of players that Liverpool have brought in in the current transfer market, their chances are better in the Champions League and if you look at it so far Liverpool are willing to spend more money to bring in one player and that means they realize how important it is to add strength next season. Mo Salah is not young anymore but his goal-scoring instinct is still quite good and I am sure that in the next season it will remain the same.
To reach the final is indeed a little more difficult because as you said and a number of other strong teams have also tried to fix the team well. But if you look at Liverpool's mentality I myself am more confident that this English representative team has the ability to compete with other representatives.
