Manchester United vs. Arsenal: Five Takeaways from the Premier League's Biggest Game of the Opening Weekend

The Gunners secured a 1-0 win away against the Red Devils, with Riccardo Calafiori’s 13th-minute header enough to hand Mikel Arteta’s side all three points.

There were things we noticed in this game, and we have taken time to share them with you.

For many years, Arsenal were seen as a team with a weak backline that could easily break under pressure. That was not the case at Old Trafford. Even though Manchester United had 62% possession and 22 shots compared to Arsenal’s nine, the Gunners stood firm. 

William Saliba and Gabriel Magalhaes led the defence with calmness and discipline, making life much easier for goalkeeper David Raya. 

This kind of defensive maturity shows that Arsenal can now win games even when they are not at their best.

United played with far more energy and creativity under new Ruben Amorim compared to last season. 

Debutants Matheus Cunha and Bryan Mbeumo added pace and movement, creating several chances that troubled Arsenal. 

Cunha dragged defenders out of position, while Mbeumo was always looking dangerous. But for all the good play, United’s biggest weakness showed again, with no consistent goalscorer to finish the chances. 

Until Amorim fixes that problem, good performances may not always lead to points.

The only goal of the game came from a corner. Declan Rice delivered a dangerous ball, United’s defence switched off, and Calafiori rose highest to score. 

While Altay Bayindir in goal for United made a costly error, Arsenal’s success from set-pieces was no accident. 

They have been well-drilled in these situations for some time now, and it often gives them an edge in tight matches. 

United, meanwhile, showed that defending set-pieces remains a weakness that could hurt them again this season.

The two goalkeepers had very different nights. United’s Bayindir, standing in for the injured Andre Onana, made the mistake that cost his side the game. His lack of command in the box during the corner was a harsh reminder of how ruthless the Premier League can be. 

At the other end, Arsenal’s Raya was excellent, making several important saves, including a strong stop from Mbeumo’s header. His calm presence gave Arsenal the platform to secure the win.

The result meant more than just three points. For Arsenal, winning 1-0 away at Old Trafford without playing their best football will boost belief in the squad. 

It showed they can now grind out results, something that defines title-winning teams. For Manchester United, the defeat was painful, but the performance showed progress. 

The energy and attacking play under Amorim were encouraging signs, though the lack of goals reminded fans of the same old problem. United are clearly improving, but they are still a work in progress.
