The Portuguese coach has made a mixed start to life at Old Trafford as he looks to put his imprint on the club but the full-back believes his compatriot will be the manager to end the club's quest for a league title win that dates back to Sir Alex Ferguson's retirement in 2013.
Dalot told United's website: "If you want me to be completely honest, with this manager, I think we can win a Premier League. I think realistically we can win. But then it becomes the most difficult thing to hear as a fan: that it will take time.
"I understand. I'm a player but, at the same time, I know what you feel. I know that this club is thirsty to win and everybody wants to win. We're not talking about cups - I know that is important, to win trophies - but what brought this club to what it is is big trophies.
"I think we can win a Premier League with this manager, but at the same time, we need to create an environment where he has everything set for what he wants from the players. We need to also adapt to the system. It will take some time.
"Obviously we cannot think too much ahead, but I'm really convinced that the way he conducts himself, the way that he communicates with players, the idea that he has... We can do it. Now it becomes the most difficult part, but being really honest and positive about it, I think we can win big trophies with this manager."
Amorim has sought to stamp his authority at Old Trafford and Dalot believes that the changes he is making will benefit the club in the long run despite the teething problems.
The defender explained: "Obviously I share every day, every moment with my teammates, with the people around the club, with the new staff as well, and you can see that there's one way to go.
"Sometimes when you are going that way, you have a lot of things that you need to change, and there's a lot of change going on at the club, and it's always difficult at this point where you want to change things but, at the same time, you need to win games. The last couple of months we have been trying to train during games, so it's been a really tough process."
