It was a routine victory for Manchester United against Swansea today as they beat the Welsh side 2-0 at Old Trafford. United were in complete control of the game and took the lead in the fifth minute through Romelu Lukaku. The Belgian was found inside the box by Alexis Sanchez and he scored his 100th Premier League goal, becoming the fifth-youngest player to reach the century mark. Sanchez then doubled the lead in the 20th minute after he was put through on goal by Jesse Lingard and the Chilean put it past a helpless Fabianski.Their tempo slowed down a bit in the second-half and Swansea showed more fighting spirit and it took some brilliance from David De Gea to keep their clean sheet intact. United themselves had a couple of big openings to add to their tally but they failed to convert them. Here's how Twitter reacted to the game.One touch. Bang. Romelu Lukaku get his 100th Premier League goal! pic.twitter.com/Vam1qPjzAH— The Man Utd Way (@TheManUtdWay) March 31, 2018Alexis Sanchez makes it 2-0.

Perfect day.— Adam (@DeGeaoIogy) March 31, 2018Lukaku has left Laca & Morata with them Ashley Barnes & Glen Murray— ~ (@Pxlvmi_A) March 31, 2018Genuinely wouldn't swap Lukaku for any striker out there right now. Has it all, can play in behind, can run off the shoulder, can take the ball to feet, world class linkup play. Bullies defenders for fun. Love this man. pic.twitter.com/k99ZTthnA8— Adam (@DeGeaoIogy) March 31, 201811 - Alexis Sanchez has both scored and assisted in 11 different Premier League games - only Romelu Lukaku and Roberto Firmino (12 each) have done so in more matches since the Chilean's debut. Busy.— OptaJoe (@OptaJoe) March 31, 2018Romelu Lukaku has just scored 100th PL goal & he’s Belgium’s all time top scorer. All at the age of 24. The abuse he gets on Twitter is ridiculous. Could become one of the best strikers ever.— Lacazettes (@Lacazettes) March 31, 2018100 Premier League goals before the age of 25. Not bad from Romelu Lukaku pic.twitter.com/yh9iQEC1KM— SportsJOE (@SportsJOE_UK) March 31, 2018Only thing Lukaku doesn't have yet is he doesn't know how to stat pad. This is the type of game he should forget about playing for the team and try to get more goals— Nduka (@Daniel_ND_) March 31, 2018Goals this season:Morata & Lacazette = 22.Lukaku = 26. pic.twitter.com/wVbTWfNsjz— Ryan. 🔴 (@Vintage_Utd) March 31, 2018Lukaku quietly banging in the goals whiles a certain someone has gone almost 100 days without a premier league goal— FELIX (@asantemans_son) March 31, 2018Sanchez was praised for his performance as well!Never seen Sanchez look so happy to score a Premier League goal. Sit down Arsenal— Mark Goldbridge (@markgoldbridge) March 31, 2018Alexis Sánchez will get it right, he wants to succeed at Manchester United you can see the determination. Next season you will see the real Alexis Sánchez a much better player that what he was at Arsenal. #mufc— United Report (@ManUtdReport_) March 31, 2018Alexis Sánchez's game by numbers vs. Swansea:68 touches49 passes3 interceptions2 chances created2 tackles won2 shots1 assist1 goalPlaying the right notes. 🎹 pic.twitter.com/A46DH2CsC9— Squawka Football (@Squawka) March 31, 2018This has been Sanchez's best performance for United so far. Apparent this season the #mufc attack functions better when only one of Sanchez, Rashford and Martial are starting.— Samuel Luckhurst (@samuelluckhurst) March 31, 2018Aside from his goal and assist, he won the ball back plenty too, much to the disappointment of Arsenal fans whose only happiness in life comes from stats showing how much Sanchez loses the ball.— Scott Patterson (@R_o_M) March 31, 2018
