"Has Salah been the same since his shoulder was dislocated by Sergio Ramos?"
However, his tally of two goals from six matches in all competitions compares to three from half-a-dozen this time previous year.
"Wow, that's a crisis", said Klopp sarcastically at his press conference on the eve of their Premier League clash with Southampton. It's really no problem.
The previous six have all ended in victory, with Klopp citing "greed", "aggression" and, latterly, "reinvented defensive skills" as key factors behind their ideal results to date in 2018-19.
"Salah is ready to work for the team and it is normal that sometimes he doesn't score", Klopp said.
This game was an example of how much a threat Liverpool are from different types of attacking play.
"Finishing is something you can never take for granted", he added.

Southampton will be without Danny Ings as he's not allowed to play against his parent club while Manolo Gabbiadini will face a late fitness test on a hamstring injury.
Klopp was asked whether the perception that Salah was not doing well was because many people expected him to repeat last season's heroics. "It is completely normal everyone expects that".
"We don't expect that". There is no game where we have thought: 'Thank God we have played them.' None of the results we have this season would have been possible without the greed you have seen or without the aggression you see. I am fine with him, I think he is fine with me and the situation, so that's all.
"We are really waiting for him without making pressure on him and we know that it will take a long time but he will always be a very important part of the squad because of the guy he is".
Ex-Arsenal defender Keown believes that Salah is not being as physical in possession anymore and speculated that the injury he sustained in the Champions League final to Real Madrid last season could still be playing on his mind.
"What was it past year?"
The Reds striker started his first Champions League game since his move to the Anfield outfit in a £12m deal from Chelsea FC in the 2013 January transfer window.
