In this context, it’s hard to push for two or three wins. We’re trying. But this game was hard on us.”Without any situation we suffered again at set-pieces. We were a little bit nervous, the stadium.Most read in Football”We controlled the rest of the first half with some clear chances, and then in the second with the penalty and then another goal is really hard on everyone here.”In this kind of moment, every thing is hard on us. The set-pieces, the penalty, then we want to score again but we are too nervous. We have to fight this.Roy Keane opens up on fight with Man Utd team-mate that was ‘brewing for years’ and admits he left him with black eye”We tried to score but in the end, it was a tough match in a tough situation. We need to move on.”Man Utd ratings vs Bournemouth as Malacia is hooked after horror first halfRUBEN AMORIM suffered his worst defeat of his short reign as Man Utd boss with a shocking 3-0 loss to Bournemouth at Old Trafford.And his flops were easily second best all over the park to Andoni Iraola’s Cherries. SunSport’s Ian Whittell has provided his ratings of the Man United squad…Andre Onana – 5Shaky on ball and his nervousness in holding it too long was transmitted to United supporters.Bad conditions for a keeper but there were also some uncertain moments when he needed two attempts to grasp on to long shots.Noussair Mazraoui – 4Complained bitterly about the penalty he gave away but it was hard to make a case in his defence.Caught out, then panicked and tripped Justin Kluivert from behind to cap what was already an uninspiring display.Harry Maguire – 4All too often was second to the ball or simply failed to get hold of his man, with Evanilson too elusive for the United defender to shackle.Ruben Amorim believes Maguire is perfect for his three-at-the-back formation but the jury is still out on that one.Lisandro Martinez – 5Stood watching as Semenyo swept in Bournemouth’s third goal, the latest in a long line of defensive embarrassments from United.Seems to be struggling, like most of his defensive team mates, with the new system and incapable of doing even the basics.Diogo Dalot – 6Made a couple of good blocks and tried to become involved in attacking moments from wing-back, without having a huge impact.On a day when United’s defence was again found wanting, however, he was not the worst culprit.Manuel UgarteBooked for a cynical foul on Kluivert and too often struggled to cope with Bournemouth runners.Too much of the game passed him by and did not last even the hour as United chased the game.Kobbie Mainoo 6Like most of his team, guilty of some unforced errors but there was no faulting his work rate or drive.Created a great chance when he hounded Dean Huijsen off the ball and set up Bruno Fernandes but gave up the ball for Bournemouth’s third.Tyrell Malacia 3Terrible touch early on drew groans from the home fans, the first of a number of sloppy moments from the fit-again full-back.Predictable that he should give away the free-kick from which the visitors opened the scoring and hooked at half-time.Amad Diallo 7The big winner from the Rashford controversy and could have lit up Old Trafford early on but placed a good chance straight at the keeper.Not a performance on a par with his derby exploits but still looked United’s best hope of carving out a goal.Bruno Fernandes 8Playing higher, and wider, up the field these days and maybe there is a debate over whether that is the best use of his undoubted talents.But in the last five minutes of the first half alone, he had three good chances which might have brought an equaliser.Joshua Zirkzee 5Given the nod ahead of Rasmus Hojlund, a reward for some decent recent performances under his new manager but this was not one of them.Was the closest Red to Dean Huijsen as he headed Bournemouth in front though United’s defending was such a mess, it was not clear whether he was Zirkzee’s responsibility.SubstitutesLeny Yoro (for Malacia, 46) 4Came on as part of a much-needed half-time defensive reshuffle by Amorim but failed to add stability.Alejandro Garnacho (for Ugarte, 54) 5Had a chance when clean through just after Bournemouth’s third but hit it straight at Kepa.Rasmus Hojlund (for Zirkzee, 54) 6Looked like he might have a goal in him and at least forced Kepa into one good stop.Substitutes (not used): Altay Bayindir, Casemiro, Toby Collyer, Christian Eriksen, Jonny Evans, Antony.
