The Red Devils legend claimed players are "micromanaged within an inch of their lives" in the modern game after a 0-0 draw in Sunday's (06.04.25) Manchester Derby.
Amorim told Sky Sports: "In this game, they are seeing the games and in our moment, with the season that we are doing, we have to accept it and this is quite fair.
"Sometimes at the end of the game, you don't like it because you are trying really hard to change things and they are talking about your players.
"But then, one day later, you can understand. It's fair and I understand what he's saying."
The 39-year-old coach argued that teams need to be "better tactically" and rely less on "individual" players than in Sir Alex Ferguson's day.
He explained: "The game is completely different and you have to be so good in your base and then that individual aspect and the freedom and the fluidity of the game is going to appear. But, for that, I think we need time.
"There was an evolution, you can like it or not, but there was an evolution because you have all the games from the opponent's detail, from your departments, so you can understand better the movements that they make.
"In that evolution, you have to be better tactically. Sometimes I talk to [Darren] Fletcher, about how he prepared the games with Sir Alex Ferguson, it's completely different."
Amorim also pointed out that while in decades past, there was a focus on "that aspect of the individual talent", you still "need to have a connection" in the team.
He added: "We need to have an idea of how to play as a team and then expect the individual part to help us.
"Because in the end, that is the crucial point to make a difference in the game."
