Man United Football Club is one of the most successful and well-known football clubs in the world. With its rich history, it has achieved numerous achievements over the years. However, despite this success, there have been some areas where the club has struggled to stay competitive. One such area is tactical reform.

Tactical reform refers to changes that the team makes to their tactics and strategies to improve their performance on the pitch. Man United has undergone several tactical reforms over the years, but one of the most significant ones was the introduction of a new defensive formation known as the "Four-Three" system.

The Four-Three system is a modern tactical approach that aims to balance the strengths of both the attacking and defensive sides of the team. The system involves four central defenders, three midfielders, and two strikers. This approach allows for a more balanced attack and defense, which can help the team to score goals more efficiently.

Another major tactical reform that the team underwent was the introduction of a new player signing, Marcus Rashford. Rashford was signed by Manchester United from Borussia Dortmund in January 2018, and he has since become one of the best players in the Premier League. His speed, agility, and ability to create scoring chances make him one of the most valuable players in the squad.

Overall, the tactical reforms that Man United has undergone have helped the team to perform better than ever before. By implementing a new defensive formation and player signings, the team has improved their overall performance on the pitch. Additionally, the introduction of a new defensive formation and player signings has also helped to strengthen the team's youth development program, making them even more competitive in the future.
