#3 Not taking defence seriously
Even after such a horrible run of form, Liverpool still are the highest scoring Premier League side, which suggests that the problems lie elsewhere: the defence. Anyone can see that quality wise, Liverpool's defence is very average but Klopp did not do enough to bolster it.
He has played Lucas Leiva, who is primarily a midfielder, in defence, but let Mamadou Sakho leave on loan due to a breakdown in their relationship! Sorry, Klopp, I might be one of your biggest fans but you have to take the blame for this.
Dejan Lovren is at best a backup defender for a team like Liverpool, and the same goes for summer signing, Ragnar Klavan. There is no one good enough to partner Joel Matip at the heart of the defence.
Now let us take a look at Liverpool’s left-back problems which have not been sorted out since the Rodgers era. Alberto Moreno is a defender who cannot defend while James Milner’s performances at left-back have been steady, but hardly special.
