In other matches, Brighton and Hobe Albion secured a 1-0 win over Everton, Cardiff City stunned Leicester City by the same scoreline and the spoils were shared between Watford and Newcastle after their 1-1 draw.
The goalkeeper's anticipation, vision and technique allowed him to ping a volley out from his own area and launch the attack that led to Liverpool's fourth strike in first-half stoppage-time.
It was Tottenham's third match in seven days over Christmas and it showed in the second half as Wolves knocked the stuffing out of them. This season, Klopp has adapted that style a little bit. It's still about preparing [for] football matches, play them as good as you can and try to get as many points as you can. Would they wilt under the pressure or would this just fire them up more?
If you put these guys in yellow shirts, you could mistake them for the Dortmund side (which won the Bundesliga under Klopp in 2011 and 2012).
"I said to Aboubakar Kamara to leave the ball to Mitrovic, he is the man who shoots the penalties", said Ranieri.
There's a belief, not only in Liverpool, but in the opposition that they can't beat this side, or at least it's going to be really, really tough.More news: LeBron James out vs. Kings; games streak ends at 156

- Liverpool are now unbeaten in 31 Premier League games at Anfield (W22 D9), their joint-longest ever unbeaten home run in the competition, having also gone 31 without defeat between December 2007 and August 2009.
However, the lead only lasted three minutes as Firmino scored his first home goal of the campaign in the Premier League with a typical no-look tap into the empty net after benefiting from a ricochet inside the Arsenal box.
The two against Arsenal were far more concrete than the one against Newcastle, with Greek centre half Sokratis having not one, not two but three hacks at Salah's ankles before the Egyptian went down and the second was weird, Kolasinac just deciding to shove Lovren to the floor rather than defend properly. But you are the first if we drop three points and the next headline is: 'Are they nervous now?' That's an easy job.
The potential to do it was always there because last season there were too many daft results. They're the best team when things get loose and it's anyone's.
The form of Lucas Torreira had me anxious in that respect but Liverpool's no.5, Gini Wijnaldum, absolutely bossed the Uruguayan all night.
Klopp said: "Fabinho hit two very average passes and he was shaky in the next couple of moments".
