Manchester United's performance on the pitch can be significantly affected by the decisions made by their referee during games. A poor decision from the referee can lead to a loss of points, which can have a significant impact on the team's overall standing in the league and potentially even their chances of winning major tournaments.

One of the most common types of decisions that referees make is regarding fouls or penalties. These decisions can be crucial for Manchester United's success as they try to maintain possession of the ball and score goals. If a foul or penalty is not given to Manchester United, it can result in them losing possession of the ball, which can then open up opportunities for the opposing team to take advantage.

Another type of decision that can affect Manchester United's performance is related to red cards. When a player receives a red card, it can severely limit the team's options on the field. This can be especially detrimental if Manchester United has already been behind by a goal or two and needs to find a way to come back.

In addition to these decisions, there are also times when the referee makes controversial calls that can affect Manchester United's performance. For example, if the referee gives a free kick too far away from the goal line, this can give the opposing team an easy opportunity to score. Similarly, if the referee awards a corner kick outside of the penalty area, it can allow the opposing team to gain possession and create scoring opportunities.

Overall, Manchester United's performance on the pitch can be greatly impacted by the decisions made by their referee. It is important for the team to understand how these decisions can affect their performance and work with the referee to ensure that their best interests are being represented. By doing so, Manchester United can improve their chances of success on the pitch and ultimately achieve their goals.
