Liverpool held on to win 3-2 at Prenton Park, but still...
But, while many questioned Karius' position as Liverpool's number one, Klopp backed his man ahead of the new season, but the latest instalment of his goalkeeping mishaps may force Klopp into the transfer market ahead of the new season next month.
"No-one likes that goal but if we talk about the second goal I think it was Millie's (James Milner's) fault together with (Pedro) Chirvella".
"Two brilliant footballers make this mistake, but we don't talk about it".
It was another bad mistake that seems to suggest Karius is struggling to throw off the psychological scarring he sustained against Real Madrid in the Champions League final at the end of last season.
Jurgen Klopp insists that "mistakes happen" after goalkeeper Loris Karius once again gifted the opposition an easy goal in Liverpool's second pre-season outing. So let's carry on and make the best of these situations to learn from them, ' Klopp said after the Tranmere game.
"You (the media) can all stop it immediately - promise?"
The former Borussia Dortmund manager added that he believes that Karius will continue to be criticised until "he has a few fantastic games". That you [the media] do what you do, we have to deal with it.
"The boss is asking me to do a job as a right-back for him".
"The boys, we need them. I would be really insane if I would not give these boys a chance - they are fantastic players, they've played fantastic games, so we will see what happens".
