No doubt Manchester United's forward looks much better this season compared to last season's mess, but the defensive line still lacks that composure in defending goals from their opponent.
Amorim has been able to tackle the problem of the attack though they still haven't done any significant thing in the game because the team is performing well up front but no goals to show for it but the defense line needs a serious work because the team can't be conceding cheap goals when they are still still finding it difficult to score even against weak opponents.
Manchester United's problem is some of the cheap goals they conceded against teams that they should be able to beat with 3-0 or 2-0. Manchester United's attack is good this season because all of the games Manchester United has played so far, the attackers played well. One of Manchester United's major problems is the goalkeeper. Manchester United don't have a good goalkeeper that can make saves that will make the defence improve their performance, When the custodian is unable to make simple saves the defense will suffer.
Another issue with Manchester United is the coach, Ruben Amorim, who should stop using Amad as a right back because he cannot defend like a normal right back. Amad should be a substitute when they need a goal, and when Mbuemo does not perform well or has an injury, Mazraoui is back and he is a good right back; that style of play will not help Manchester United, and if Ruben Amorim continues to use Amad in that position, the team will continue to lose matches.
