Well, that will depend a lot on this Summer and what results the officials draw from this truly terrible season. If anything, Klopp certainly has earned himself enough credit to rebuild the squad and try to make the necessary adjustments to make them successful again.
I could write a whole essay about the problems they have right now, because they are basically all over the pitch. From the lack of width due to the poor form and limitations of the Fullbacks over the lack of depth in the central midfield (they have currently exactly one player, who can give them structure and they miss him so much that it is not even funny) to the way too static offensive with too much focus towards the center. The defense is basically the only thing that improved since the winter break, but they struggle immensively to create chances. The absolute lack of threat via set pieces does not help either, which is quite frankly mindblowing given that this was a major strength of them just last season and helped to break down heavy defense lines.
I can see a major overhaul coming in the Summer, because they are too many players who have shown themselves to being part on the team more on the basis of merit than performances. Players, who were part of the successful campaigns in the past, but who stagnated or even reverted for far too long. Weidenfeller, Subotic, Schmelzer, Piscu, Bender... The list is quite long. On top of that I can see players like Mkhitaryan and Ramos leaving to finance the necessary signings. I don´t see throwing money on the market as the right way, though. Maybe it is time to go back building on what created the team in the first place: young, hungry players, who can be moulded into the necessary pieces of the puzzle. The development of talent is still one of Klopp´s biggest strengths and for that a season without International football might actually be a blessing in disguise.
In the end it was probably only a matter of time until a real rebuilding had to take place to stay on top of the game.
