Manchester United has only won seven of their 29 matches. The manager needs to be criticized for this. Perhaps it wasn't fair to criticize him last year, but this year they haven't won a single match. They drew one and lost the other. This is why Manchester United is experiencing a worsening performance. They need to straighten out this downward spiral. Of course, this will require radical decisions and significant spending.
The reason is only our expectations towards the performance of Manchester United as they poorly failed to perform in the last season. But i personally think that in this season they deserve sometimes to cure themselves and heal their performance. It is true that they failed to win a single match in this season but they are not alone in this line. The stage they came from they need much to improve. Because now no other well player is in the situation to join the Manchester United. So they really need to develop their confidence first and try to make the things smooth for their improvements. And we really need to expect less according to their situation but I believe they will get success to resume their performance from their peak times.
