The Liverpool poor performance is from the coach, not really from the players, because Liverpool team have a qualified players that can play well in competition, but the problem is the coach featuring them in a normal position they are supposed to fixe to make well, let us use Chelsea as an example, since Chang coach and bring in Abraham potter they have never perform well, they are still using the same method of football style. So the performance of a team lies on the arrangement of the coach
I think it's quite normal that after great performances in the past years you also have a phase in which things go poorly.
Under Jürgen Klopp, Liverpool won some major titles
(CL, PL, FA Cup etc.). I don't think it makes sense to fire the coach now just because things are going badly at the beginning of this season. We are only on the 8th matchday and I think you should give the coach and of course the team (!) time to adjust to the current situation.
It seems as if the absolute will to win has been lost at the moment
(that happens, especially if you won all these major titles in the past). Pretty games and brilliant Liverpool gameplay seems to be over for the moment. Its time for hard work.
We should see how the situation develops over the next few weeks and only then draw the necessary conclusions. Personally, I am pretty sure Jürgen Klopp can bring Liverpool back on track. However, it is also clear that the current performance is not enough and something urgently needs to change.
