MANCHESTER UNITED RATINGS: Andre Onana - 5: Has conceded more than one goal in the last four league games, the first time this has happened in 44 years. It also meant United’s excellent home run of wins came to an end. Only got his fingers to the third, a finish that was going away from him. Fine save from Fati at the end. Reuters
Diogo Dalot - 6: Third straight league start. Subject of a yellow card tackle by Lampety after three minutes. Top play to set up Rashford on 25. Nicked ball off Mitoma to stop a 48th-minute attack. Another who didn’t do enough to stop the second goal conceded. Reuters
Victor Lindelof - 5: Ball ran by him before Brighton took the lead in a big setback after a bright start. Smart ball to Rashford to set up one attack. Did well to keep the ball when Lallana threatened to run at goal on 42. Getty
Lisandro Martinez - 5: Backed off and didn’t do enough to stop the cross for the first – a fine Welbeck finish. Static for Brighton’s second goal from Gross and, like Casemiro, a star player who has dipped this season. Getty
Sergio Reguilon - 5: Combined well with Rashford on the left at the start, but part of a defence that was continually carved open by Brighton. Getty
Casemiro - 5. Too casual and didn’t make a recovery run for Welbeck’s goal. Didn’t have the legs you need against Brighton. Disappointing so far this season. What on earth has happened? AP
Scott McTominay - 5: First start of the season for his club. Didn’t do enough to stop Brighton’s second and struggled to stop them dominating possession. EPA
Bruno Fernandes - 5: Began on the right of a midfield, which started well, but got deeper and deeper against the best team to visit Old Trafford so far this season. Booked before the break. AFP
Christian Eriksen - 6. Beautiful pirouette to start a ninth- minute attack as United started on the front foot with high pressing. Tried to set up attacks for United who had 14 shots, but only four on target. Brighton had 10 shots – eight on target. AP
Marcus Rashford - 6: Drove into the box from the left. Took the first shot on target in the game – and the second after 11 minutes. And the third after 25, then the fourth, which hit the post on 33. Another shot went wide on 46. PA
Rasmus Hojlund - 6: Aggressive on his first United start, getting in front of Dunk for early crosses. Thought he’d scored after 40 minutes. VAR didn’t. Linked well with Rashford. Decision to bring him off was booed. Getty
SUBS: Hannibal Mejbri (for Casemiro on 64') - 7: Pulled one back with a shot on the half turn from distance nine minutes later. Booked for a challenge on Ferguson, but a determined cameo. AFP
Anthony Martial (for Hojlund 64') - 4: Almost no impact. AP
Alejandro Garnacho (for McTominay 85') - NR: Fans had sung his name. He came on as a last gamble. It was all too late. Getty
Aaron Wan-Bissaka (for Reguillon on 85') - NR: Went to right back. Getty
Facundo Pellistri (for Martinez on 85') - NR: Is he ever going to get sufficient minutes to show what he can really do, or not do? AP
BRIGHTON RATINGS: Jason Steele - 7: Great distribution with his feet. Good anticipation to come out of his box and deny Rashford an opportunity from a long ball. Easy save from long-range Fernandes effort and another good stop from a Rashford free kick. No chance for Hannibal's goal. EPA
Joel Veltman - 6: Given a tough time by the pace of Rashford at times but made a vital block to deflect the United forward's first-half shot against the woodwork. Generally comfortable with the ball at his feet. Wasted a good chance to play Welbeck in from the edge of the area. Fiercely committed. EPA
Jan Paul van Hecke - 8: Strong headed clearance from a United corner on 34 minutes. Twice managed to shepherd Rashford well as he broke into the box early in the second half. Snuffed out an opening for Hojlund. Getty
Lewis Dunk - 8: Solid in the heart of the Brighton defence. Cool under pressure and distributed well. Impressive shift. EPA
Tariq Lamptey - 7: Neat work on the left flank. Came forward well and involved in some well-worked passing moves out wide. Lovely ball to tee up Joao Pedro for Brighton's third. EPA
Pascal Gross - 9: Fresh from his first senior cap for Germany aged 32, he was the midfield kingpin for his team, linking up play and spraying passes before finishing brilliantly for Brighton's second. Reuters
Mahmoud Dahoud - 6: Battled well on his first start since the opening game at Luton. PA
Simon Adingra - 6: Put Onana under pressure early in the second half with some sharp pressing. Showed great anticipation to cut out a dangerous cross-field pass. Allowed Reguilon to wriggle past him late in the game. EPA
Adam Lallana - 7: Nice dummy to assist Welbeck's opener. Pressed United's backline well. Worked hard defensively. Getty
Kaoru Mitoma - 7: Harried the United defence well. Quiet game until he helped to set up Gross's goal. Surging run into the box in the 78th minute. EPA
Danny Welbeck - 8: Sweet left-foot finish for Brighton's opener after he'd played the ball wide for cross into the box. Went close with a crisp strike from outside the box on 32 minutes. Held the ball up well and dropped back to put in a shift helping out his defence when required. AFP
SUBS: Joao Pedro (for Welbeck 64') - 8: Stunning side-footed finish from the edge of the box. Wonderful technique. Looked good in everything he did. EPA
Ansu Fati (for Lallana 64') - 7: Set up Evan Ferguson on the edge of the area. Decent strike just inside the box that forced a sharp save from Onana. Another lightning quick run to force a save in added time. Promising debut. EPA
James Milner (for Lamptey 76') - NR. Good clearing header in the box. EPA
