Arsenal beat Manchester United 2-0 at the Emirates stadium in the feature game of the Premier League weekend. Granit Xhaka and Pierre Emerick-Aubameyang were on the score sheet for the hosts, who also kept just their sixth clean sheet of the season. The win took Arsenal to fourth position, while Manchester United dropped to fifth.In the first half, Arsenal started on a positive and found themselves in promising positions. But it was Manchester United who had the best chance inside the first 10 minutes, when Romelu Lukaku hit the cross bar after Luke Shaw had put in an excellent cross from the left. However, Arsenal drew first blood with Xhaka's fierce strike deceiving David de Gea from distance. Then, Manchester United hit the post again - this time it was Fred's low-drilled shot from about 22-23 yards out.United created a host of chances, but couldn't find the final touch. Lukaku then missed a one-on-one opportunity, with full credit going to Bernd Leno for the save. United were edging closer to an equalizer, but Arsenal held on in the first half. In the second 45, the Red Devils started on top again. Lukaku missed another easy chance after Rashford found him with well-tuned pass. Arsenal then came back into the match a little bit and got a penalty through Alexandre Lacazette. Up stepped Aubameyang and put it away to make it 2-0 and put the game beyond doubt. Solskjaer introduced some attacking changes then, bringing on Mason Greenwood and Anthony Martial, but Arsenal then held on to give the Norwegian his first loss in the Premier League. This can be termed as just a bad day at the office for Manchester United, but Arsenal were brilliant on the day.Here's how Twitter reacted to Arsenal's massive win over Manchester United.HALF TIME - Arsenal 1-0 Manchester UnitedThe Reds go in behind at the break but should be level considering some of the opportunities we've had.Players seem a little fatigued, could do with freshening it up a little.

Not going to lay in to him for the pen. He didn’t even make a challenge. The referee isn’t even bent. He’s just dreadful at his job. Dive all day long.— Scott Patterson (@R_o_M) March 10, 2019United so bad today OGS can easily say ‘bad day at office’ and move on. Clearly has to be one off or season will unravel quite quickly.— Simon Stone (@sistoney67) March 10, 2019Cool as ice #ARSMUN pic.twitter.com/eMZv6YwFqL— Premier League (@premierleague) March 10, 2019Emery removing Ole's Wheel pic.twitter.com/c6kvA927it— Troll Football (@TrollFootball) March 10, 2019
