Manchester United fans are delighted with midfielder Scott McTominay's performance against Arsenal in the Premier League today (September 4).The Scottish midfielder has had to deal with harsh criticism since the beginning of last season for his consistently poor performances. However, he has been in good form in recent matches and helped his side to a 3-1 win over Arsenal at Old Trafford.McTominay, 25, made four clearances and two tackles. He registered a 100% passing accuracy and also completed the one dribble he attempted.Manchester United have signed Casemiro from Real Madrid for around £70 million this summer. Many expected that this would mean a lack of playing time for McTominay, but that hasn't been the case so far.After the win against the Gunners, the Old Trafford faithful took to Twitter to appreciate the academy graduate.

He was incredible The apologies better be as loud as the disrespect.415Looks like McTominay starting worked out extremely well. He was incredible The apologies better be as loud as the disrespect.McTominay has played 176 senior matches for the Red Devils, scoring 16 goals and providing four assists.He was linked with a move away from the club after they signed Casemiro with clubs like Newcastle United and West Ham United amongst other clubs interested (via the Manchester Evening News). However, if he continues performing well, he might become an integral part of Erik ten Hag's side.Arsenal fall for first time this season against Manchester UnitedAfter winning all five of their matches so far, Mikel Arteta's side came up short against Manchester United at Old Trafford.They had the ball in the back of the net via a stunning finish from Gabriel Martinelli in the 11th minute. However, VAR disallowed the goal due to Martin Odegaard's foul on Christian Eriksen during the build-up.Manchester United's new signing Antony then scored in the 35th minute via a neat finish after being left unmarked in the Arsenal box.Arsenal did well at the start of the second half and were rewarded in the 60th minute when Bukayo Saka scored his first goal of the season.However, the parity lasted just six minutes as Marcus Rashford put the Red Devils into the lead again in the 66th minute after an exquisite pass from Bruno Fernandes. The England international scored his second of the game nine minutes later as Eriksen squared it off to him in the box for an easy finish.Arteta's side still sit at the top of the Premier League table, one point above Manchester City and Tottenham Hotspur. Manchester United are fifth in the table, one point behind Brighton & Hove Albion.Both teams will now turn their attention to their respective Europa league group stage fixtures. Arsenal will travel to face FC Zurich while United host Real Sociedad, both on Thursday, September 8.
