BOURNEMOUTH finally took top Billing at the Theatre of Dreams – on another miserable day for Manchester United.

The Cherries had never won at Old Trafford before and had only ever been ahead there on one other occasion.

Yet Andoni Iraola’s men went in front inside five minutes here through Dominic Solanke and barely looked back all afternoon.

Danish midfielder Philip Billing made the points safe before Marcos Senesi completed United’s humiliation.

At the start of a week which could define their season, it could not have been much more embarrassing for Erik ten Hag’s men.

They were booed off and now face a Champions League salvage mission on Tuesday night against Bayern Munich and then travel to Liverpool next Sunday.

Just when they looked to be turning a corner, it is back to square one for the Red Devils.

And to think Ten Hag was celebrating winning manager of the month just 24 hours before this horror show.

The former Ajax boss sprang a surprise in his team selection by leaving both Marcus Rashford and big money summer buy Rasmus Hojlund on the bench.

Starting instead was the much-maligned Anthony Martial – a move that left the regulars scratching their heads.

Bournemouth have never won at Old Trafford – but arrived in decent form having won three and drawn one of their last four games.

It was only the second time the Cherries have been in front at the Theatre of Dreams – with the last time coming in 2020 when they ended up losing 5-2.

United tried to hit straight back with Harry Maguire sending a looping header that had to be touched over by Neto.

But Bournemouth were defending well while also posing a threat of their own on the break.

And in many ways United were fortunate to only be a goal behind at the break.

Iraola’s men were certainly good value for their lead – while United had rarely looked like adding to their meagre tally of 18 goals for the season.

Ten Hag chose to not to make any changes at half-time but by 10 minutes after the restart he had seen enough.

His decision to replace Martial with Hojlund was greeted by the loudest cheer of the afternoon by the home fans.

The £72million arrival from Atalanta has yet to break his duck in the Premier League but his arrival was a welcome sight.

McTominay – the two goal hero against Chelsea – could have rescued United again but this time his header was straight at Neto.

Hojlund saw a goalbound effort blocked while Diogo Dalot fired a shot into the side-netting when he surely should have crossed.

Yet the visitors were dealing comfortably with the threats posed by the home side and still looking useful going forward.

And midway through the second half they doubled their lead as a pass from Luke Shaw was intercepted by Solanke who worked it out to Tavernier.

His cross to the back post found Billing who easily outjumped Shaw to head beyond Onana.

Old Trafford was stunned into silence – but worse was to follow just five minutes later.

Tavernier’s corner from the right found the head of Senesi who was virtually unmarked as he thumped an emphatic header into the corner.

That was the cue for many fans to head for the exits – a seventh league defeat of the campaign.

Deep into stoppage time a stray pass from Amrabat saw Bournemouth in again and Dango Outtara bundled the ball home.

Fortunately for United, the ball had hit the Burkina Faso player’s hand and the VAR had ruled it out.

The unfortunate aspect was that it would not have even slightly pleased the guests. United was fortunate to escape with three points.
