Nottingham Forest manager Dougie Freedman says he wants to change a culture at the club in which "nobody seems to leave".
The Reds are under a Financial Fair Play (FFP) embargo which limits their transfer market activity.
"The culture has been one of 'I am comfortable, I sit here and if I don't play, I don't play', which I am trying to change," said 41-year-old Freedman.
"The criticism I will make is that it has never been a one in, one out."
Forest are restricted to 24 senior professionals at the club under FFP rules and Freedman suggests youth will be given the chance this season.
"It takes time, it's patience that you have got to have, with your youngsters and with the football club," the former Bolton Wanderers and Crystal Palace boss told BBC Radio Nottingham.
"We need to share the vision with each other and that can take us more forward than we have been doing.
"We have a manager who will play young players, I just hope the fans are patient with them."
Teenage striker Tyler Walker made his first-team debut last season and scored against Brentford after coming on as a substitute.
Youngsters Dimitar Evtimov, Roger Riera and Jorge Grant have also been around the first team and involved in pre-season.
Freedman continued: "I understand it is results, I get that, but I just hope the fans understand what the club are going to have to do.
"I don't think the way they have been doing it in the last three or four years is the right way.
"They've tried to buy success and I really think you've got to have a mixture in there and, if the fans are patient with the youngsters, it will give them a chance to succeed."
