Steve Cooper says that his team must "thrive off the challenge" of playing in the premier league for the first time in 23 years.
The club is considered to be one of the favorites to be demoted.
Cooper said they really believed in their work.
Despite being bottom of the Championship, Forest were able to return to the top flight.
Cooper came in as Hughton's replacement and led the team to promotion.
In the 1998-99 campaign, Forest finished bottom of the table.
Cooper said that there were a number of emotions.
Everyone is looking forward to the challenge of the premier league, it has been a long time coming
There is focused attention. It will be incredibly difficult and we are under no illusions. Everyone is making sure they are prepared. We need to believe in ourselves. Why should anyone else if we don't.
To thrive off the challenge, you have to do it. Many players and staff are trying to get a chance in the premier league Negative emotions are not something we want to have.
We believe in what we can do and that we can beat any opponent. The approach and other objectives will be internal.
Cooper has spent more than 100 million dollars on 12 players this summer, including some eye-catching deals.
Awoniyi has joined the club from Union Berlin for a club record 18 million dollars, while Richards has joined from the German club.
There have been changes in the squad. It looks like we are changing everything around, but we have had no other choice.
Jesse Lingard and Dean Henderson have joined on free transfers after leaving Manchester United.
After their loan deals came to an end, they will not be able to compete. The two men have signed for different teams, with one returning to Manchester United and the other going to Spurs.
There are a number of things that make a player want to join the club. You feel it every day at the club. The size of the club is one of the things players look at.
They know exactly what the club is about and we have tried to thrive off that, at the same time trying to create a new era for the club.
