Dyche made the comments before being appointed Nottingham Forest boss, with United to meet Forest this weekend.
Amorim said: "First of all, maybe it's true if we play 4-4-2 we win more, but I always said that I have a way of playing that is going to take a while.
"Then I can look at Sean Dyche as a manager and then as a pundit. If you are a pundit and you don't say very strong things, I don't want to watch you! So I can understand that it's a different job. I know that Sean Dyche is really smart and he knows how to play the game.
"He also understands that one thing is when we are seeing the game and talking about the game, the other thing is to coach a team.
"So I understand that, I have nothing to say, I just want to win the next game."
