What Ruben Amorim did was very appropriate because he certainly had analyzed the factors why Manchester United often failed to be consistent every season. Maybe some people will consider Amorim a little selfish for his decision not to involve Ruud van Nistelrooy and a number of staff, but if seen from the positive side Amorim has started a good decision and wants to maximize this opportunity purely under his system.
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.
The decision made by Amorim not to involve Ruud van Nistelrooy in his coaching at Manchester United was not wrong. Instead, he showed strong optimism and self-confidence not to depend on other coaches. He showed his strong desire to fight with all the staff he had formed himself. So yeah it was a brave decision I think. And of course Amorim also shows a strong mentality in this matter. I hope he doesn't get too much pressure at the start. Because I want him to be more focused and really be able to wake up the strength of Manchester United which was sleeping. I miss Manchester United who are back to being a very strong team. Even though I'm not a Manchester United fan, I still like this team. Under Ruud's brief coaching, everything seems to be going well and I hope that continues under Amorim's coaching.
