First thing i'll do if I'm Klopp is to sack that high defense line immediately.
It just doesn't work anymore because teams have sussed us out. Plus, that high line is effective only when we've got our midfield switched on. Fabs is off-form. Gini is no longer there to 'ghost' between the lines and provide cover when necessary. Too easy to break that high line of ours.
But i suspect Klopp and co has thought of this before too. The problem is how would you then setup your defense and team, if we remove the high line ? We always play and build from the back, so if our defense sit deeper, we lose that extra bit of pace in our game, especially in getting the ball as quickly as possible to our front three. Unless you plan to go route one and ping hollywood passes quickly to our front three, when we counter. I suppose, that may work, cos that would mean we bypass our non-existent midfield. But long-term it won't work, plus that's just not how we play - ugly football.
Alright, if you don't go route one, and you still wanna build from the back, but without the high line, you'd have to change formation. You'd need a holding or defensive midfield, to link midfield and defense. Fabs seem the most likely candidate, but how would you then setup your midfield ?
Option 1
Trent -- Matip/Konate -- VVD/JoeGo -- Robbo/Greek
-------------------------Fabs------------------
------Hendo-----------------------Thiago
Salah----------------Nunez--------------------Cody
Look at this formation. Lack of width. That's why we play with the high line even though it comes with a risk. Because our system is setup so that our FBs can bomb forward and overlap to provide the width. They're essentially WBs really, but opposition have worked out how to nullify that threat by 1) crowding the midfield or 2) place forwards on the shoulders of our high line (esp. Trent's side) and play quick triangular 1-2s to easily bypass Trent.
It wasn't easy before for opposition teams because we had that 'ghost' Gini and an in-form Fabs providing quick cover previously. So now you can understand why Trent's the easy target, because his natural instinct is to always go forward.
I really don't have an answer to this problem because i think we don't have the right players. We're crying out for a top-class midfielder and we ain't got one yet.
PS: My english is all over the place in this post, so pardon me. Maybe someone can rephrase my points a lot better.
