FIRST HALF - CHAOTIC ENDING
Despite being buoyed by Harry Maguire and Luke Shaw being declared fit to start, it was a nervy start by the Reds, as Newcastle's confident approach belied their run of three successive domestic losses at home.
In only the fourth minute, Lammens and Leny Yoro opted to leave a hopeful cross by Kieran Trippier that bounced off the frame of the goal, with Lewis Hall lashing the rebound off target.
Although Matheus Cunha hit a wayward shot and then supplied a dangerous cross that was not in the middle, the vast majority of the attacks were coming towards Lammens's goal.
Former Red Anthony Elanga hit a volley on the full from Yoro's header out but it dropped well off target and was left by Lammens. Seconds later, Casemiro won the ball in his own box but was tackled by compatriot Joelinton, allowing Gordon to touch off to Harvey Barnes, who swung an effort narrowly wide, as the home fans waited for the net to bulge.
There was no VAR intervention when Dan Burn appeared to elbow Shaw, leaving him in some pain, and the stoppage only temporarily halted the pressure. Sandro Tonali thrashed a loose Noussair Mazraoui clearance wide and it took Benjamin Sesko almost squeezing his way through at the other end to give the noisy away supporters something to truly get behind.
From a free-kick of some promise for United, the hosts broke instead and Joelinton worked an angle, only to blaze over from outside the area.
Our first shot on target of the half was worth the wait as, in the 42nd minute, Yoro found Sesko, who kept possession and picked out Mbeumo. The Cameroon international invited Kobbie Mainoo to try a shot and it was curling away from Aaron Ramsdale, who justified his inclusion ahead of Nick Pope by diving to claw it away superbly.
We should then have edged in front when Cunha cut through the defence and forced another save out of Ramsdale. This time, he pushed it against Burn and it ricocheted to Mbeumo, who really should have scored but fired into the crowd.
Back up the other end, Ramsey went down too easily when Lammens raced from his goal and was shown a second yellow card, for simulation, by referee Peter Bankes. Instead of boosting the Reds, though, the Magpies charged through again and Gordon forced his way between Mazraoui and Fernandes, going to ground. Referee Bankes saw enough in it to award a penalty and Gordon slammed past Lammens for the opener.
In the ninth minute of stoppage time, Fernandes floated in a free-kick after Mazraoui was fouled and Casemiro applied the finishing touch with a simple nod of his head, to spark fury from the stands.
