This is the worst stats for a Premier League manager I have witnessed. How bad Manchester United have been this past years, looking at this stats I can agree that Amorim is not as good as persons hype him to be honestly. Any other manager could do better than Amorim with the current squad.
Don't judge Ruben Amorim base on the last season when he inherited a dieing team from Ten Hag that was at the edge of collapse. We have to be a bit patient for him for the season to go halfway and all stones can be cast on him should the bad record of last season repeats for this season where he was given money to buy the players he was in request of. Objectively speaking there is an improved play in Manchester United team except that they are yet to win a match in two matches played which is no big deal to call for his sack.
