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. Manchester United management needs to think of long term management, were the manager is given enough time to assemble his team and work with them without interference from them the management, I just think they need to stop this hiring and firing.
Yeah you are right Manchester United shouldn't think of sacking there coach now because his still doing very well I think the longer he stays in the club the more the club will keep growing and becoming more stronger he's doing well and I see no reason for them to sack him however if the club is not performing well this season they should sack him because they have given him the opportunity to buy the players he needs in other to make the club stronger so I see no reason why the club should be performing in a low form or being down in the premier League table like last season.
For now judging from their last match this season with Arsenal I will say that Manchester United is now inform and strong and they have every chance to lift the premier League title all they need is to be consistent and grow more stronger yes Arsenal won them, however they played very well and had more chance of scoring goals so I believe that next match they will do more better, even if they don't lift any trophy this season but they performs well the coach should remain in the club because I believe that the future is great for them.
