New Rotherham manager Ronnie Moore says the club has a three-year plan to make it into the Championship.
Moore is back as Millers boss for the second time having guided them from the old Division Three to Division One during his first spell.
And that is a feat the club's board expect him to repeat.
He told BBC Look North: "The ambitions of the board and chairman are unbelievable. They want us to be in the Championship in three years."
Moore, sacked as Tranmere boss in June, replaces Mark Robins who took over at Barnsley earlier this month.
During his first period as Rotherham manager between 1997 and 2005 the 56-year-old masterminded back-to-back promotions.
He said he was delighted to be given the chance to mirror that achievement.
"It's fantastic to be back," he said.
"When the chairman said to me 'send your CV in and we'll take a look,' I thought there was no way I was going to get the job.
"So there's a lot of satisfaction knowing that I've gone through the selection process with 50 other applicants and got the job.
"There will be supporters saying this is just a sentimental appointment but it's not sentimental for the chairman. He's given me the job because I'm the best man for the job and I hope to show the supporters I'm the man to take Rotherham back where they should be."
