MANCHESTER UNITED held their nerve to see off Chelsea despite a late fightback at Old Trafford. Robert Sanchez was sent off after five minute before goals from Bruno Fernandes and Casemiro gave United a 2-0 half-time lead. GettyCasemiro’s goal separated the sides[/caption]But Casemiro was also sent off to even the playing field and despite Trevoh Chalobah pulling one back – United held firm. Here is how Katherine Walsh rated Ruben Amorim‘s men from the Theatre of Dreams. Altay Bayindir – 5His launched punt put Chelsea in all sorts of trouble when Robert Sanchez was sent off for flying out of the box to take down Mbeumo. Stood all alone as the heavens opened in Manchester as the keeper endured a quiet first-half with United producing their best start to a game of the season.Was left vulnerable and flat footed for Chalobah’s pulled back header from five yards. His team-mates just can’t deal with corners.GettyAltay Bayindir helped Utd open the scoring[/caption]Noussair Mazraoui – 7United can count themselves lucky that the Moroccan is back in action.The wing-back’s cross was headed back by Dorgu for Bruno Fernandes’ opener and he never put a foot wrong. United were considerably more shaky when he came off.Winger-like run through the Chelsea midfield but the water-logged pitch was his biggest opponent tonight. The crucial tackle stopped 2-1 by the hour mark.AFPUtd can count themselves lucky that Noussair Mazraoui is back in action[/caption]Matthijs De Ligt – 8His big interventions won United the game.The Dutch star pushed high up the pitch with United dominating so much early on. And he produced some key passes as his team reigned on the ball.The centre-back produced the best defensive clearance of the ball to deny Chelsea a goal back quickly after the break.GettyMatthijs de Ligt was stellar against Chelsea[/caption]Harry Maguire – 6Maguire failed to sure things up at the Etihad last week but he should definitely start in a back-two pairing with De Ligt moving forward.He played a key role in all areas of the pitch, almost setting up Fernandes on the stroke of half-time. More shaky when United were down to 10 after his misplaced ball put Chelsea through on goal.APHarry Maguire played a key role in all areas of the pitch[/caption]Luke Shaw – 6Was a surprise starter after his poor showing at the Etihad but this was a much better Shaw. The full-back assisted Casemiro’s goal with a header in the box and had choice words with Enzo Fernandez after the celebrations. Was up there in the strongest before his bizarrely fumbled pass was picked up by Reece James in the final seconds. ReutersLuke Shaw improved against Chelsea[/caption]Bruno Fernandes – 7Almost cried when he broke the deadlock inside 16 minutes with a clever poachers finish following a lengthy offside review from VAR.With his team dominating 10-man Chelsea, Fernandes wasn’t forced to play in his deeper role so often. Dropped into midfield after United lost Casemiro and was unlucky to be stopped by a great Filip Jorgensen save in the last 10.GettyBruno Fernandes opened the scoring[/caption]Patrick Dorgu – 6Crosses were much better placed than his City showing last Sunday and he set up the second.Was perhaps lucky that Reece James launched his poor header in the air before Casemiro doubled the home side’s lead. But some silly mistakes almost cost his team-mates.PAPatrick Dorgu showed signs of improvements[/caption]Amad Diallo – 5Is the winger lacking in confidence? Amad got his feet mixed up and failed to hit a cross from a few yards, instead waiting and pulling the ball out of play as United’s second was ruled out.Minutes later the 24-year-old made the wrong decision again when he failed to shoot with acres of space, instead trying to find Sesko in the box. Feel like a broken record but the Ivorian again overfired an easy cross into Sesko which could have seen United 3-0 up before half-time.His mess ups proved costly as Chelsea pushed in the second half. Was weak in the final seconds when he pulled out of a challenge with Chalobah who sent the ball up.Shutterstock EditorialAmad Diallo looked to be lacking confidence[/caption]Casemiro – 3Why Casemiro, just why? The Brazilian made history for all the wrong reasons.His goal and sending off make him the first Man Utd player to score and be sent off in the same half off football in a Premier League match.The supposed most experienced man on the pitch showed naivety to be sent off in the fifth minute of first-half injury time – especially after his back post header doubled United’s lead 10 minutes before.The first booking came from a needless foul on Enzo Fernandez , while the second was somewhat unfortunate as he grappled Andrey Santos from behind before winning the ball. ReutersCasemiro went from hero to zero after his sending off[/caption]Bryan Mbeumo – 7So crucial to everything United do going forward and relieves Fernandes off the set-piece duties, although they were poorly dispatched at times.His sprint forced Sanchez into action for the sending off but the Brentford star later air-kicked a brilliant cross in a good position.APBryan Mbeumo was vital to Utd’s win[/caption]Benjamin Sesko – 7This is what Sesko can bring to his game that Rasmus Hojlund couldn’t.The 6ft 5in out -jumped Chelsea defender Trevor Chalboah to flick on Mbeumo’s run through on goal which led to Sanchez flying out and his workrate shone throughout. Was sacrificed at half-time after Casemiro’s red.AlamyBenjamin Sesko showed more positives signs[/caption]SUBSManuel Ugarte (for Sesko, 46) – 3Amorim had to replace one foul-ridden midfielder for another. But the former PSG couldn’t get a grip of the game. His awful miskick from a corner put Chelsea through in the last 10 minutes.Matheus Cunha (for Mbeumo, 61) – 5Fans were thrilled to see the Brazilian back from injury. He played off Fernandes well. Leny Yoro (for Maguire, 70 ) – 3Wasn’t in the tempo of the game and fell asleep while marking Chalobah’s pull back.Mason Mount (On 70′): N/AKobbie Mainoo (On 87′): N/A
