The Manchester United Coach made multiple unfavorable decisions for his team. Looking at the beginning of the game Man U came out strong, but great changes occurred in the field after Rashford left the pitch due to red card. What stopped the coach from substituting for a better player who can handle the defense of the team? Allowing a 2:2 equalization in the first half, shows, indeed, how bad the defense became. On the one side, I'd say that Man United belittled the power of their opponent, that was why they lost the game. Because, looking at their attacking force, they felt relaxed believing that they'll win after adding 3:2 to the game. Copenhagen became wild around 80 minutes where they dealt with Man U and defeated them. It was too late for Man u to bounce back, because they already felt winning was on their side. Both the players and the coach didn't add extra effort in winning the game. Wan Bissaki happened to be the only hardworking player from the man united side. He applied energy and skill in his game, but to no avail. Many of his team mates didn't realize the power of moving all defense, after they scored their third goal. Look at how Tottenham worked hard against Chelsea after receiving 2 red cards. Despite losing the game, you'd notice the energy and skills they exerted towards Chelsea. Manchester United wasn't that way in their game.
