Former Stockport manager Ray Mathias has decided to leave the club.
The 64-year-old was replaced as County boss by Dietmar Hamann last week, after a consortium headed by Tony Evans took control at Edgeley Park.
Mathias told BBC Radio Manchester: "The club put a proposal to me and I put a proposal to them, which was negotiable.
"They came back to me and said my proposal wasn't right, so we parted company on good terms. I'm so disappointed to be leaving the club."
Mathias was only given the job on a permanent basis on 25 May after taking over from caretaker boss Peter Ward in March.
Although the former Wigan and Tranmere boss could not prevent County's relegation from League Two, he was making preparations for life in the Blue Square Bet Premier, before a Liverpool-based consortium headed by Evans launched their investment.
"They've got an investor in the football club which was needed," Mathias said.
"So I think its important they got this person in to start running the club now - hopefully they can be a success.
"Hopefully they can plough some money into the football club. The most important thing is getting the right players to take you up in that league."
It was initially thought that Mathias would take up another position at the club but a deal could not be agreed between the two parties.
He continued: "I'm a little bit sad but I enjoyed my time there.
"It was absolutely fantastic, a lovely family club - the fans were absolutely brilliant, I couldn't ask for any more from them.
"I had a good rapport with the fans and with everybody round the football club and I was absolutely delighted when I got the job.
"I would have worked my socks off to try and get them back in the Football League."
