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.
If they are thinking of firing Ruben Amorin I really think it's too early for such decision Ruben Amorin took over from Erik Ten Hang at half of the season where the team is almost nothing to write home about, no trusted player to count on or have in mind that maybe with him the team is somehow confident, no player like that but he managed to reach the Europa League final despite losing it to Tottenham Hotspurs, but that's not enough reason to fire him, he's just brought in some new players that everyone is happy and hoping to achieve something with them they want to fire him? That's not fair at least they should let him manage for this season if there's nothing good then they can fire him.
