After a disappointing 2024-2025 season, Manchester United has regained faith when Michael Carrick took over the coaching bench from Ruben Amorim in January and helped the team finish in the top 3 of the Premier League. However, to truly return to the position of a championship contender, the "Red Devils" still have a lot of work to do, especially in force building.
Before the 2026 summer transfer window, many opinions suggested that the defense was the line that needed the least additions for Man United. However, recent developments have shown the opposite.
In theory, Man United has many options in the center of defense with Matthijs de Ligt, Lisandro Martinez, Harry Maguire, Leny Yoro and Ayden Heaven. However, the biggest problem lies in the ability to maintain the fitness of the key players.

De Ligt has not yet been able to return after a prolonged back injury since November last year. The recovery process of the Dutch center-back is quite slow, and even the goal of reappearing in October this year is not certain.
Meanwhile, Lisandro Martinez continues to worry fans after getting injured in the 2026 World Cup final. Although there is no official conclusion on the severity, the dense injury history of the Argentine international makes Man United unable to rest assured.
Harry Maguire has revived strongly in the past two seasons, but the English center-back is no longer young. Leny Yoro and Ayden Heaven both possess great potential, but still lack experience to shoulder the defense for a long season in many competitions.
Therefore, adding a quality center-back is still considered a priority for the Old Trafford home team.
On both wings, Man United has more rotation options. Luke Shaw has just experienced a rare season of stable performance when participating in all 38 matches in the Premier League. However, with the English defender's injury history, the coaching staff can hardly expect him to continue to maintain a similar fitness foundation when the next season's schedule is more dense.
Patrick Dorgu can take on the left-back position if needed, although his forte is playing higher. Besides, Diogo Dalot and Noussair Mazraoui are also capable of playing on both wings, giving Carrick more options in rotation phases.

In the goalkeeper position, the "Red Devils" brought in Karl Darlow to play a backup role for Senne Lammens. Meanwhile, Altay Bayindir is likely to leave the team, and young goalkeeper Radek Vitek also wants to leave on loan or official transfer to look for regular playing opportunities.
In general, Man United's defense is not lacking in quantity but there are still many questions about depth and stability. If they want to compete for titles in the 2026-2027 season, Michael Carrick's team will need an additional reliable center-back to minimize the risks from the continuous injuries of key players.
