Manchester United's refereeing challenges have been a topic of discussion for many years now, with the club facing criticism over their performance in games where their referee has made controversial decisions.

One of the most notable examples was the match against Manchester City at Old Trafford in January 2019, when United were awarded a penalty by referee Michael Oliver despite the ball hitting the hand of City player Leroy Sané. The penalty was subsequently missed by United's forward Anthony Martial, who had his chance to score but failed to do so.

This incident sparked controversy among fans and media alike, with some arguing that the decision was harsh and unjust. However, others defended the referee's judgment, pointing out that it was not clear whether the ball had touched Sané's hand or not.

Regardless of the outcome, this incident highlighted the impact of refereeing challenges on team performance and game outcomes. It showed how even small mistakes can lead to major consequences, and how referees' judgments can be crucial in determining the outcome of a match.

In addition to the match against Manchester City, there have been other instances where Manchester United's refereeing challenges have led to negative outcomes. For example, in the 2018-19 season, the club faced criticism after they lost a game against Arsenal due to a controversial penalty awarded to Arsenal in the second half.

These incidents demonstrate the importance of having a fair and impartial refereeing system in football. It is essential that referees make accurate judgments based on the evidence available, without any personal biases or prejudices influencing their decisions.

In conclusion, Manchester United's refereeing challenges have had a significant impact on team performance and game outcomes. While these incidents may spark debate and criticism, it is important to remember that referees play a crucial role in ensuring fairness and justice in football. By maintaining a fair and impartial refereeing system, we can ensure that all teams have an equal opportunity to compete and win.
