Manchester United management can decide to keep the manager or fire him after considering how Manchester United performed under their manager last season. After taking charge of Manchester United team last season, the manager could not bring any player to the club but this season Manchester United has brought three new players to the club so Manchester United should have confidence in this manager for the entire season. If Manchester United manager fails to bring his team to a good position this season then the decision can be taken to remove this manager. But if the management decides to remove this manager now then it will definitely be an injustice to this manager.
Yeah, Manchester United shouldn't even think of firing him even though he brings nothing back home at the end of this season.
I agree with you when you said that even though he brings nothing back home at the end of this season, because he needs time. Looking at their previous match against arsenal is clear that there are a lot of changes in the club so i believe if he continue with this maybe by next season he may likely bring back the manchester united we used to know back then so is just a matter of time, I believe the man would definitely make changes in the club and I feel that amorim is the best Manager for manchester united. so they shouldn't even think of firing him, Moreover he have not even manage manchester united for 1 full season so we can't start judging him when we have not even test him for a complete season.
