Karius came in for criticism, and Klopp came out swinging when defending him. Goalkeepers can always be a big test for any manager.
Liverpool manager Jürgen Klopp faces a big test of his management right now given the goalkeeping situation at the club. Loris Karius has struggled in games against Bournemouth and Southampton and looks badly out of form. Criticism is coming from all angles.
It's of little surprise that Klopp has come out on the attack. He had to try and move the story on from Loris Karius and it looks as though he has succeeded with his riposte to the Neville brothers.
Klopp is quoted in the Liverpool Echo, saying: "The pundits are the former players a lot of them and forgot obviously completely how it felt when they got criticised.
"Especially the Neville brothers who I have to say really, the one who was the manager (Gary) he obviously should know that too much criticism never helps - but he's not interested in helping a Liverpool player I can imagine."

The reason it seemed Liverpool entered the market for Karius was to provide better competition in the goalkeeping department, and try to eradicate the errors coming from the back - something which Simon Mignolet has been guilty of when trusted with the gloves. Unfortunately for Karius, he's been making those errors too.
Klopp explicitly said that Karius was his number one - and ever since Mignolet has been limited to two appearances in the EFL Cup.
Managing goalkeepers can be a very hard task, it's getting a little harder for Klopp right now given his summer signing seems indecisive and is making errors. Mignolet would be right to question when it's his turn to be reinstated. On the face of it there was some improvement from him at the start of the season, and he wasn't immediately dropped when Karius returned to fitness. More like he was phased out.

The build-up of fixtures towards the end of this month and in January could work in Klopp's favour. Both goalkeepers are going to get their fair share of game time, even if the gloves for the number one keeper don't necessarily change hands.
Yet there would be an opportunity, should he wish to do so, to make a change in goal that wouldn't attract so much fuss, and more importantly wouldn't rock the confidence of his current number one.
However, more than anything, Karius could do with a clean sheet when Liverpool travel to Riverside Stadium to take on Middlesbrough on Wednesday night.
