Salah took his goal tally to 36 in just his 41st appearance of the season by netting four as Liverpool thrashed the Hornets 5-0 on Saturday.
Subsequently, talk of the prolific No.11 - who also registered an assist for Roberto Firmino - dominated the post-match discourse at Anfield.
Captain Jordan Henderson labelled Salah ‘outstanding’, Joe Gomez said his influence on the Reds was ‘indescribable’, while Steven Gerrard admitted ‘it’s difficult to find new words’ to describe the Egyptian’s brilliance.
Klopp’s praise of Salah was similarly effusive, but the boss first reminded Liverpoolfc.com that he achieved the same feat as his top scorer during his playing days - scoring four in a 5-0 win for Mainz over Erfurt.

“Maybe I should start like this: I scored four goals in a game as well, in 1991. You can find it on YouTube [but] I’m not sure we had recorded games in those times!” the manager joked after being asked to assess Salah’s display.
“Let’s come back to Mo now! He was fantastic, of course, really fantastic.
“The way he scored the goals… the conditions were unbelievably difficult with a little bit of snow on [the pitch] and it was slippy, the ball slowed down, stuff like that.
“Around the first goal there was exactly one person who has no problem with that and that was Mo. He scored the goal and that helped us a lot.
“The second goal was a fantastic situation. Sadio’s super pass and Robbo with a fantastic cross and Mo uses his speed.

“It helped a lot and coming out of the half-time break, the third goal, Roberto’s, it was not even a real chance in the first moment and he [Salah] uses his body, the defender is a little bit behind him then he uses his speed and he sees Roberto coming to the first post. So that’s a fantastic goal as well.
“The next two - just outstanding. The greed is so obvious, he wants to score, he wants to score but he doesn’t forget the others, if you see the situation with Danny Ings.
“[Ings] was a little bit unlucky, but it’s still nice to watch that he is really good and really strong at the moment. Dom Solanke [was] not in the squad, that’s unbelievable. I have no explanation for that, to be honest, apart from that I can only take 16 plus two goalkeepers so it’s just good.
“We scored the goals, obviously very important goals for us, and it’s a very impressive result.”
