Yes therefore in order to become champions liverpool need to improve the quality of the game. Liverpool defense is still very fragile, in the next transfer window I believe liverpool will buy defender.
Thry need a goalkeeper and that is always their main problem, I have seen that sometimes even with top defender on your side there is no guarantee how things will turn however if they got a handy of defender alongside a top goalkeeper than that would be the best choice for their problem
I think there is no problem with Loris Karius. The game increased over time. If properly trained and have better hours of flying, I'm sure Karius would be the best goalkeeper. In the previous match he played very well and did not go wrong if Klopp appointed him as first-choice goalkeeper liverpool because it has good quality. The problem of liverpool is defense, because the goalkeeper as good as any if its defense is not good definitely be overwhelmed.
