Why are you continuously dragging Klopp into financial discussions? He bought Nunez for €100m and nearly bought Caicedo for €115m last summer. Klopp gets what he wants; the only difference between him and Pep is that players often reject his project (Caicedo).
Fans are mostly idiots who don't actually follow what's happening. Arsenal was working on a really tight budget at the time and it's not even an opinion - it's a fact.
Most managers in top clubs buy good players. If you think Klopp didn't overachieve with Liverpool (and Dortmund), I really don't know how to continue the conversation
Winning 1 EPL title and 2 domestic cups in eight years after spending almost as much as Pep did is not overachieving; you're only exaggerating because Liverpool were irrelevant for far too long before Klopp. Nobody is denying that he did well at Liverpool; he won everything; yet, using the term "overachieved" to describe someone who won only one league trophy in eight years is absurd.
I am not going to talk about Euro trophies because Tuchel won them all in less than 18 months. Facts only.
