First-half goals from Dwight Gayle and Sean Longstaff paved the way for Newcastle to condemn the Cherries to a third successive defeat since the Premier League resumed.

Gayle opened the scoring after five minutes before Longstaff doubled the visitors’ lead in the 30^th minute.

Eddie Howe’s team were left with a mountain to climb after Miguel Almiron came off the bench to make it 3-0 after 57 minutes before fellow substitute Valentino Lazaro completed the away side's scoring 13 minutes from time.

Dan Gosling, a second-half substitute, bagged the Cherries a consolation with virtually the last action of the game, bundling home from close range. 

Lloyd Kelly was handed his full Premier League debut as Cherries boss Howe made four changes following the 1-0 defeat at Wolves.

Kelly, who came off the bench at Molineux having had an injury-interrupted first campaign with the club, started at left-back with Adam Smith switching to the right.

Joshua King was declared fit having missed the Wolves game due to injury and he partnered Dominic Solanke in the Cherries attack.

Arnaut Danjuma, who has come off the bench in the Cherries’ two games since the restart, was drafted in for his first start since December.

Jack Stacey, Lewis Cook and Junior Stanislas dropped to the bench, while Callum Wilson served the first of a two-match suspension having totted up ten bookings.

Aaron Ramsdale saved bravely at the feet of Gayle after the Newcastle striker had chased down a long ball into the 18-yard box early on.

However, Gayle drew first blood in the fifth minute when he profited after the ball had fallen to Allan Saint-Maximim following a challenge between Jefferson Lerma and Sean Longstaff.

After the ball had squirmed loose to Saint-Maximim, he slipped it into the path of Gayle who finished clinically by drilling a low right-foot shot into the bottom corner, giving Ramsdale no chance.

As the Cherries looked for an immediate response, a sweeping move down the left flank ended with Philip Billing clipping his effort over the crossbar following good work by Danjuma.

Solanke lifted a difficult chance wide of the target after David Brooks’s free-kick had been headed back into the danger zone by Adam Smith.

Billing received the first booking of the game for a foul on Longstaff, although the free-kick was dealt with by the Cherries defence.

Newcastle doubled their lead in the 30^th minute when Longstaff rifled the ball into the roof of the net from close range after Saint-Maximim had teed him up following a jinking run into the six-yard box.  

A presentable chance to halve the arrears bit the dust when Danjuma blazed a free-kick over the crossbar from a promising position on the edge of the box.

As the first half drew to a close, Nathan Ake followed Billing into referee Kevin Friend's notebook for a foul on Newcastle substitute Almiron, who had replaced goalscorer Longstaff.

Lewis Cook replaced Billing at the break and the Cherries thought they had scored, only for King’s header to be ruled out for offside just seconds after the restart.

Ramsdale had to be on his toes to parry Saint-Maximim’s stinging low drive, the Cherries goalkeeper scooping the Frenchman’s effort out for a corner.

Although the Cherries applied some pressure to the Newcastle defence, the visitors extended their lead through Almiron in the 57^th minute.

The Paraguay international beat Ramsdale with a delightful right-footed strike, clipping the ball past the Cherries goalkeeper from the edge of the box.

Brooks was picked out by Lewis Cook and tried his luck from 20 yards, only to see his shot skim the top of the crossbar.

A double substitution on 62 minutes saw Brooks and Danjuma replaced by Harry Wilson and Stanislas with Gayle and Saint-Maximim making way for Andy Carroll and Lazaro.

Lerma, who was walking a disciplinary tightrope on nine bookings, was replaced by Gosling after 75 minutes, the Colombia international now off the hook should he collect one more yellow card.

Lazaro added a fourth for the Magpies when he fastened on to a slide-rule pass from Jonjo Shelvey before firing an angled drive past Ramsdale in the 77^th minute.

And it could have been worse for the Cherries when Isaac Hayden blazed the rebound high and wide after Lazaro’s fierce effort had come back off the underside of the crossbar.

In the closing stages, a low drive from Stanislas was deflected past the post, while a glancing header from King flew over the crossbar and Ramsdale beat away Carroll's thunderous drive.

Deep in added time, Gosling netted the Cherries a consolation when he bundled the ball home from close range after Ake had headed Stanislas's free-kick back across the goal.
