Manchester United, under the guidance of manager Ole Gunnar Solskjaer, have made several tactical changes in recent weeks that could revolutionize their performance on the pitch.

One of the most significant changes is the inclusion of Harry Maguire at the heart of the defense. The England international has been a key player for Manchester United since his arrival from Leicester City in 2016, but he has struggled with injuries in recent seasons. However, Maguire's return to the starting lineup has given United a much-needed boost at the back, with the defender providing stability and leadership to the team.

Another key change has come at the expense of Paul Pogba, who has struggled with form and fitness in recent months. Solskjaer has shifted Pogba to a more advanced role as a playmaker, where he can link up the midfield and attack the opposition defense. This move has allowed Pogba to发挥她的创造力和组织能力，并为球队带来更多的机会。

In addition to these changes, Solskjaer has also implemented a new defensive system that emphasizes the importance of getting forward quickly and pressing high. This approach has led to more attacking options for the team, as players like Marcus Rashford and Anthony Martial have been able to cut through defences more easily.

Overall, Manchester United's tactical changes under Solskjaer have shown promise, and they will be looking to build on this momentum in upcoming matches. With Maguire and Pogba back in form, and a new defensive system in place, there is reason to believe that Manchester United can compete with the top teams in the Premier League.
