With the 2017/18 Premier League Golden Boot award nearly certainly now in the bag, Salah will be beginning to start thinking about his summer endeavours - where he will represent Egypt at the World Cup.
"That's how football should be, so I'm really happy with the performance", Liverpool manager Juergen Klopp said. I don't think that Mo or anybody else wants to be compared with Lionel Messi. "We have beaten them for a start".
Salah even defied the slippery conditions of a snow storm as he weaved his way past Jose Holebas to slot home the opener after just four minutes.
And manager Javi Gracia admitted his side had been completely outclassed.
"Mo is on a fantastic way. but how it always is in life, if you have the skills then you have to show it constantly", Klopp added.
"We know we were playing against one of the best teams in Europe at this moment and they were much better than us".
After his 25th Premier League score, Salah came back for more.
The winger also helped guide Egypt to their first World Cup finals in over a quarter of a century when he netted a 95th-minute penalty in a 2-1 win over Congo.
"Don't go to the papers telling everyone you're a great team".
He is also a five-time Ballon d'Or victor.
Victory moved Klopp's men back above Tottenham Hotspur into third in the Premier League as they moved a step closer to securing Champions League football next season via a top-four finish.
You would never expect the opposition striker to apologise to you after scoring four goals against you. Salah dribbled into the box, juking Miguel Britos to the ground, before beating Karnezis inside the near post.
43 mins: Salah taps in a cross from the left from Robertson on the stroke of half-time.
Salah notched his hat-trick after he again danced his way past Watford's hapless players inside the penalty area, before cutting inside to give himself literally half a yard to shoot whilst falling over.
Mane found Salah down the right flank.
"Yes, I think Mo is on the way", he said. I still weep every time I see that red shirt on him, it should be blue. The guy is absolutely lit.
