Old Trafford is no longer an invincible fortress as before, especially when the home team has just gone through a terrible season.
This match is not simply a competition between two traditional teams of English football, it also has an important meaning in shaping the mentality and motivation for the upcoming season. Arsenal are eager for the title, while Manchester United are going through an important transition period.
Both teams are facing a tense start to the season when Arsenal have a tough away trip to Old Trafford, followed by matches against Liverpool, Newcastle, Man City. Meanwhile, after the "Gunners", Man United will face big opponents such as Manchester City and Chelsea in the first 5 weeks.
Man United are going through a particularly important transition period. With Jonny Evans retiring, Man United now have no player in the squad who has won the Premier League, for the first time since the 1992-93 season. They also have no players who have played under Sir Alex Ferguson. This marks the end of an era and the beginning of a new chapter in the history of the Old Trafford team.

After 3 consecutive second-place seasons, Arsenal have prepared carefully with new players such as Viktor Gyokeres, Martin Zubimendi, Noni Madueke and Christian Norgaard. However, Mikel Arteta is still missing names like Leandro Trossard and Gabriel Jesus in the upcoming match.
As for Man United, they finished last season in 15th place, the worst record in Premier League history and did not have a ticket to the European Cup. After entering the mid-season, Ruben Amorim has now had time to prepare and has been invested heavily by the board when bringing in 3 notable new players: Benjamin Sesko, Matheus Cunha and Bryan Mbeumo. The new thorn of the "Red Devils" is to regain the strength of Man United's attack in the 2025-2026 season.
Currently, Man United has just welcomed the return of goalkeepers Andre Onana, Joshua Zirkzee and Ayden Heaven. The only absentee is centre-back Lisandro Martinez with a long-term injury. Meanwhile, Arsenal are only missing Gabriel Jesus due to an ACL injury.
In terms of the game, Arsenal will be rated much higher than Man United. Mikel Arteta's side have shown remarkable progress over the seasons and are always present in the title race. The "Gunners" are likely to continue to build a tight ball control style of play, imposing the game situation through creative coordination from the midfield and wing.

With a 4-3-3 formation or a 4-3-2-1 variation, Arsenal is still very strong in creating great pressure and taking advantage of flank attacks. In addition, set pieces are also a particularly dangerous weapon for The Gunners. With the arrival of Viktor Gyokeres, Arsenal have filled the void of the striker position they have long lacked.
On the other side of the front line, Ruben Amorim has been steadfast with a 3-4-3 formation or a variation of 3-4-2-1 with a fast pace, changing to a flexible state. It is likely that Man United will still keep a slow flow and continuously rotate the ball with a large number of players in the midfield area, along with the ability to stretch the edge of the 2 wing-backs.
In addition, Amorim's team will mainly wait for counter-attacks to create scoring opportunities. New signings Mbeumo and Cunha are likely to start. They have the same speed, dribbling ability and experience in the Premier League, this is the most dangerous weapon for Man United.
Meanwhile, Benjamin Sesko's ability to start is still uncertain as the Slovene striker has only been at Old Trafford for a few days. Leaving the Slovenia new signing to debut against a strong opponent like Arsenal will be a gamble for Ruben Amorim.

This match can be decided by many different factors. First is the ability to adapt quickly to the Premier League's pace after the pre-season. Second is mental preparation, the team that is more confident and determined will have the advantage. Third is the tactical factor with the battle of wits between Ruben Amorim and Mikel Arteta.
The result of the match will not only affect the position on the rankings, it will also have a great impact on the psychology of both teams in the following matches. Both Man United and Arsenal have a difficult schedule at this stage, a good start will give them great motivation and vice versa.
