#4 Manchester United's lack of composure in front of goal costs them again:

Manchester United started the game with high intensity and seemed determined to get the first goal. Quick movement and precise one-touch passes between the front three caused Barcelona loads of problems in the opening stages of the game. They could have taken the lead in the first couple of minutes of the game but Marcus Rashford hit the cross-bar. Scott Mctominay had another opportunity but a poor first touch let him down.
Manchester United players have lacked the composure to score in front of goal lately. They had a couple of opportunities in the first leg which they failed to take and the story was the same this time around too. If the visitors were clinical in front of the goal, the result could have different.
