Graham Kavanagh plans a overhaul of the Carlisle squad following relegation from League One.
The Cumbrians lost their third tier status with a 3-0 defeat to champions Wolves at Molineux.
Kavanagh still has a year left on the contract that he signed when he succeeded Greg Abbott last September and he is determined to turnaround the club's fortunes next season.
He said: "I am going to look at the signings I need to make and I am not going to put numbers on it because I don't know yet what is available in terms of budget.
"I have an idea of what I want to improve but I haven't told the players yet in regard to who's staying and who's going. So until I do that I am not going to divulge too much information. But there will be changes.
"I felt all the way through that that this squad wasn't good enough when I initially got the job.
"Then when I took over I thought I was working miracles and I thought the new ideas that we implemented were very much coming to fruition and we were a better team.
"That was the case for long periods. I wouldn't say that we played brilliant in all the games but we had a platform and structure that we played to and people were prepared to listen and do the work that was needed.
"Once we started to get injuries and one or two of the leaders and characters came out of the group they couldn't cope and that was very much evident today in the way that we conceded ground.
"We have played against a very, very good Wolves team and I want to give them credit because Kenny (Jackett) has assembled a very good side with a big squad but you have to produce - and fair play he has.
"I knew it would be a difficult game regardless of where we are in the table. But some of the decisions we made and the fear we played with - the lack of confidence and belief. There wasn't anyone prepared to take the game by the scruff of the neck.
"The players need to understand what it means to play for the club and what is expected of them. The fans expect us to work hard and put your body on the line.
"I think that any professional footballer should be prepared to do that. If not, they are going to find themselves on the scrapheap - as some of them may find this season.
"They have had their opportunities and not taken them. I have said to one of two of them there, including the lads who will be with us here next season, I am expecting more and demanding more and if you are not going to give it you are not going to play."
