Manchester United beat Leeds United 5-1 at Old Trafford in their opening game of the Premier League 2021/22 season. Bruno Fernandes scored a hat-trick while Mason Greenwood and Fred chipped in too, while Luke Ayling pulled one back for the visitors.The Red Devils broke the deadlock half an hour into the game through Fernandes and could have scored more given their dominance in the match. Ayling's stunning effort from outside the area in the 48th minute leveled the proceedings, giving the Peacocks some hope of a comeback.But a spectacular implosion in the defense squished it all, with the home side netting four more goals in the space of just 16 minutes.A whirlwind start to the campaign for Manchester United. Here are their player ratings:David de Gea - 7.5/10A solid game for the Spaniard who made some good saves and distributed the ball excellently as well. He could do nothing about Ayling's strike but that was the only black mark in a pristine copybook.Aaron Wan-Bissaka - 8/10Wan-Bissaka linked up with the Manchester United forwards to devastating effect and looked composed on the ball too.Victor Lindelof - 8/10The Swede didn't put a foot wrong in the match and even assisted Fernandes for his third goal. Five clearances to his credit too.Harry Maguire - 7/10He was given a hard time on a few occasions by Leeds United's marauding forwards, but kept his composure and didn't make any mistakes. Three clearances and one interception too for the Manchester United skipper.Luke Shaw - 8/10Shaw merely continued from where he left off last season, putting up a phenomenal display on the left flank. He laid out two key passes.Scott McTominay - 7.5/10A near flawless performance from McTominay, who dealt well with Leeds United's fast start and then got more involved in the attack, laying two long balls and one key pass.Fred - 8/10Fred only played one pre-season game but turned in a performance to suggest that didn't matter. Confident on the ball and crucial in breaking down Leeds United's play, he also made two interceptions and one clearance, whilst also scoring a goal.David James - 7/10His commitment was unquestionable, but James lacked the cutting edge in the final third.Bruno Fernandes - 10/10We're exhausted of superlatives to describe this guy. Another stupendous display with an opening day hat-trick. And interestingly, none of the goals were penalties! End of 'Penandes' memes?HAT-TRICK FOR BRUNO FERNANDES! 👑 pic.twitter.com/94gord7Ah1— Goal (@goal) August 14, 2021Paul Pogba - 10/10A midfield masterclass from the midfield metronome himself, who bagged four assists on the night, tearing Leeds United apart with his ingenuity.
