I also think that what Ruben Amorim did was not wrong at all because apart from wanting to maximize the performance of the Manchester United team itself purely through his own guidance, he probably did not want to be considered as someone who still depended on the old coaching staff when he coached the Manchester United team. So what he decided was actually the result of his own thinking because he had more confidence to make better changes with his own staff at Manchester United.
Manchester United no longer in ruins this season, they're getting better, their position on the EPL table is temporary and it would be progressive as time goes on. The former Sporting CP headcoach, Amorim is been appointed the current manager for the Red Devils, he's here to filled in the vacant shoes of the former Manchester United coach, Erik Ten Hag. Manchester United new coach, Ruben Amorim getting all stage hype already in his arrival at Old Trafford. This is weigh too much for the new coach because there are restraining factors that would pin him down when he faces fierce oppositions. We're not talking about only elite rivals but average clubs will exert tough displays. Amorim made his reasons known when he subjected to utilizing his own staffs and turning down Ruud van Nistelrooy management, everyone incharge gets to make decision.
It is often said that calm seas or oceans does not make great sailors, so, in an office where there are no challenges, then the manager there will likely be a very weak person.
Ruben amorin should know that he took up a fiace challenge when he decided to coach the red devils, many people, even some opposition clubs were happy seeing that Manchester united was falling below and below, atleast for them, that was a great opportunity for their own rise, and seeing that Amorin is now the new coach and things have turned promising again for Manchester united, they will try all they can to give him a good tough time, but if he will stand his ground and don't get frustrated at any point, but focus on making only good decisions for himself, the club and the management of Manchester united, trust that he will have a very good time and career with the red devils.
