Manchester United is facing ongoing issues not due to their tactical system, but rather personnel mismanagement, particularly player positioning. Despite improvements in team compactness and shape under manager Ruben Amorim’s 3-4-2-1 formation, critical errors such as missed player marking have led to consistent goal concessions. The loss against Manchester City highlighted these problems, notably Bruno Fernandes’ ineffective defensive contributions and players like Luke Shaw being out of their natural positions, affecting overall team performance. Even though United has shown potential in their previous matches, failure to correctly align their key players in suitable roles could result in repeated mistakes, limiting their chances of success in the Premier League.
