Amorim is convinced Fernandes is set for a big campaign this new season.
He told MUTV after Saturday's triumph: "It was so clear last season, you can see it with the goals and assists. But it's not just that. I think now he has more players, I feel, to help him to lead the group and that is a good thing.
"He is our leader and really important, not just on the field, but off the field. He leads by example. He works really hard, is always available and, sometimes, he plays with pain. Sometimes, the problem is he gets frustrated and loses a little bit of focus of his job.
"Sometimes, he wants to help the team-mates so much, it is not the best thing to do. They have to do their job and Bruno has, for example, to wait for the ball."
On Fernandes' position, Amorim also said: "He has a function or a position for every game. It's impossible to play all the positions. Last year, I felt sometimes I pushed him back to have more possession in the build-up and we miss Bruno near the box.
"With different characteristics from Bryan (Mbeumo) and Matheus Cunha, and I really like Kobbie Mainoo's game, he will have more help this season. Bruno runs a lot, maybe in the sprints, he is a different player but he runs a lot. He has a lot of endurance and he is smart.
"It's not about that. Physicality with Bruno is not a concern, playing him deep or as an attacking midfielder."
