FSG probably wouldn't sack Klopp if we finished 4th. And most people on here wouldn't want Klopp sacked even if we didn't get top 4.
However, there's a difference between finsihing 4th after competing, getting close and missing out.... and finishing 4th by scraping into 4th largely because the other contenders for 4th are worse.
The main thing though is that Klopp shows no signs of learning anything about how to improve the defence. We are only 6 points behind 2nd place. Given the forward line we have/had we should be much closer. But the failure to addreess the goalkeeping situation and the defence in 3 years has cost us. We have wasted yet another opportunity. Coutinho has gone and nobody will be surprised if Salah is targetted in the summer.
Seems like most in here wanted him gone after 2 losses.
But anyway, the buggest issue is, like you say, the failure to address the obvious and to persist with shitte. He hasn't looked like addressing it in the 5 transfer windows we've had so I don't see why he will in the future.
Hopefully they'll bin him before the summer but if not you can bet your life that Migs will still be here and fighting with Karius for the number one spot and Moreno will be starting LB. We'll have bought about three more AM players though so all will be well.
