The Reds were looking to record a 14th successive Premier League victory against Steve Bruce’s men in Saturday’s early kick-off at Anfield.
But Newcastle broke the deadlock in the seventh minute when Jetro Willem broke past Trent Alexander-Arnold and found the top corner with his shot.
Liverpool FC didn’t panic and Sadio Mane levelled the Premier League clash in the 28th minute when the Senegal international curled a finish into the net.
Substitute Roberto Firmino teed up Mane to score his second goal before half-time to settle Liverpool FC’s nerves following a slow start.
The Brazilian forward produced a moment of magic to unlock the Newcastle defence and tee up Mohamed Salah to put the result beyond doubt.
Pizzuti, the wife of Liverpool FC owner John W Henry, was quick to heap praise on Klopp’s players following their excellent start to the campaign.
Pizzuti wrote on Twitter: “Five premier league matches so far, and five wins for Liverpool. The strong start continues for LFC after today’s 3-1 victory over Newcastle”
