The modern game is fast-paced, competitive and constantly evolving. To remain relevant, football clubs must adapt their tactics to keep up with the demands of the game. Manchester United has undergone several tactical reforms in recent years to improve its performance on the pitch.

One of the most significant changes was the implementation of a 4-2-3-1 formation by manager Ole Gunnar Solskjaer in the 2019/20 season. This formation allowed for greater flexibility in midfield, with players such as Paul Pogba and Bruno Fernandes able to play multiple positions. The formation also allowed for more attacking options, with players like Anthony Martial and Marcus Rashford able to operate in advanced positions.

Another important change was the introduction of a new defensive system under Solskjaer. The team adopted a high pressing approach, with defenders pushing forward to win back possession and create chances. This system required players to have excellent physicality and positional awareness, which is something that many of the club's current squad possess.

In addition to these changes, Manchester United has also made use of technology to analyze and improve its tactics. The club has invested heavily in data analysis software, which allows managers and coaches to track player performances and identify areas for improvement.

Overall, Manchester United's tactical reforms have helped the team to stay at the forefront of the Premier League. With a strong focus on creativity, aggression and positional intelligence, the Red Devils are well-positioned to compete against some of the top teams in Europe.
