The Red Devils won the match through a Fernandes penalty at 90+7" and they have moved to 9th position. Manchester United was not fantastic in the game because they struggled to gain those points. But this win is a morale booster for them to keep improving and winning games. It's also a relief for coach Ruben Amorim, who is close to being sacked due to poor performance. I also don't think that the club's expenses on players this season are a waste because they need time to get used to the style of play.
This win was indeed crucial for boosting the mentality and confidence of the Manchester United players, but I believe their performance was still very poor, and this victory was not solely due to Manchester United's luck.
Ruben Amorin must continue to work hard to improve Manchester United's performance in future matches, especially their midfield, which seemed confused about implementing Amorin's strategy, resulting in the team's play being disorganized in attack.
