He's had four years to sort it out and we're still nowhere near having anything close to resembling a defence.
Baffling criticism. We had a very solid defence for two seasons, won 198 pts over 2 seasons which is the most ever in the top leagues, won unprecedented number of domestic trophies (7 from the last 8 on offer), won 14 games in a row to win the most exciting title hunt ever while conceding just 4 goals during that run. Actually, in 2019 we have conceded about as many league goals as Liverpool while going through a severe injury crisis this season.
This season we are without Laporte, Kompany and Stones for most games, Zinchenko missed 2 months, Mendy is Mendy....Ederson has lost a bit of form. It's perfectly natural that we have problems in defence.
Sometimes shit seasons happen. Klopp flirted with relegation in 2014/15. Pep's ability to manage hasn't evaporated in thin air. The other week both Zidane and Klopp said about him that he is the best in the world. The worst thing as a fan base is to put him under pressure and make him leave at the end of the season or even before that. No need to press the self-destruct button.
