Rafa Benitez’s men looked a completely new team to the one who were beaten by Huddersfield last week
The Toon boss has endured a miserable start to the season, with his side losing their opening two top-flight matches and slumping to a shock defeat to Nottingham Forest in the Carabao Cup.

There has also been growing tension between Benitez and owner Mike Ashley over transfers, with their relationship close to boiling point.
But life at St James’ Park will suddenly seem that bit more bearable for Benitez after Newcastle crushed West Ham.
And it is now Slaven Bilic and the Hammers who are lurching towards an early-season crisis, having lost their first three Premier League games.
Given the troubles at both clubs, it was a nervous start at St James’, with chances few and far between.
Isaac Hayden fired one shot just over from the edge of the box, while at the other end Aaron Creswell blasted over the bar when well placed.
But it was the hosts who took the lead in the 36th minute – much to the relief of Benitez and the Toon Army.

Matt Ritchie won the ball off West Ham rookie Declan Rice, before knocking it on to Mikel Merino, who threaded through Christian Atsu with a wonderfully weighted pass.
Atsu was through on goal but unselfishly played across to Joselu.

And the £5million signing from Stoke just about beat the covering Hammers defenders to pass into an empty net for his first Newcastle goal.
After the break, Merino, Atsu and Ayoze Perez forced comfortable saves out of Joe Hart, who has now not kept a clean sheet since England’s World Cup qualifier win over Lithuania in March.
Then Toon stopper Rob Elliot was forced into a double save, beating away Cresswell’s drive, before thwarting Javier Hernandez’s follow-up, with Ciaran Clark mopping up the loose ball.

That, though, was just about as good as it got for the Hammers, with the Toon coming close to a second when Hart had to get a big paw on Ritchie’s drive.
And Benitez’s boys deserved their second when it came 16 minutes from time.
Ritchie again did the hard yards, winning the ball in the corner, playing a one-two with Hayden and then whipping it in for Clark, who headed home off the post.
And then sub Aleksandar Mitrovic added in a third in the 86th minute to send the Toon Army into dreamland.
