Wigan Athletic's new boss Gary Caldwell hopes to instil confidence into his squad, who are battling to keep their place in the Championship.
Caldwell, 32, has replaced Malky Mackay at the DW Stadium in his first managerial position.
"You want to have an effect straight away, I think any manager will tell you that," Caldwell told BBC Sport.
"You want to put your own stamp on the club, your beliefs and character, and I'll try and do that from day one."
He added: "How quickly that takes to bed into the players and show on the park, only time will tell.
"I want to go in and set a positive tone and get the belief back into the players that we can achieve things and start winning games as quick as I can."
The former Scotland centre-back, who is the youngest manager in the Football League, is Wigan's third manager of the season after Uwe Rosler and ex-Cardiff boss Mackay.
Caldwell, who was part of the Latics' 2013 FA Cup-winning squad, retired earlier this season because of a persistent hip injury but has been coaching at the club.
"I'm excited and looking forward to a huge challenge," he added. "It's something I didn't expect - to get this chance so young in my life and coaching career
"I was a player that played with desire and passion and that's something I want to bring into management."
Wigan are in danger of suffering a second relegation in three seasons and chairman David Sharpe said they have discussed plans if they drop into League One.
"As soon as I met Gary in the past couple of years I've known straight away he was a future manager of a football club and I wanted to make sure he was manager here," said Sharpe.
"It will be difficult to stay in the Championship. We're eight points adrift with five games to go, it would be a miracle if we stay up.
"We're not judging him on the next five games, it's one for the future.
"It's more for the long term. I'm not judging him over the next five games but I'm positive he'll get a reaction."
