Optimism is high for Jurgen Klopp's side, who climbed briefly into second place after beating West Ham 4-1 last Saturday, before Manchester United moved back above them with victory over Chelsea a day later.
The latest win at Anfield offered another example of the thrilling football that Liverpool have played under Klopp this season, scoring 103 goals in 40 games in all competitions.
Of those goals, 66 have been shared between the formidable front three of Mohamed Salah, Roberto Firmino and Sadio Mane.
That night, Swansea manager Carlos Carvalhal suggested that Liverpool were like a Formula One car stuck in a rush-hour traffic jam, referring to the way his players had worked to stop Salah, Firmino and Sane.

"I think we have a good basis now for the end of the season. We are third in the Premier League, we are still in the Champions League and I think we are in a very good position.
"Each game is like a final. We have to look from each game to each game and now on Saturday it will really be a very tough game against Newcastle."

"I loved it at Liverpool and will always have fond memories of my time there, but I am manager of Newcastle United now and we'll go there to try to claim three points.
