Ryan last week gave his backing to the Irish-led consortium, who are bankrolled by an anonymous Belize-based tycoon.
The 63-year-old, a life-long supporter who bought his beloved Rovers in 1999, revealed Sequentia could invest up to £40million in the club in a bid to bring Premier League football to the Keepmoat Stadium.
"It's stalled at the moment but I think Sequentia Capital are still keen to do a deal," Ryan told the Doncaster Free Press. "It's just a case of whether we can get all of our ducks in a row.
"They sent me a bank statement with £40million in it so they've got the money. We'll just have to wait and see how it turns out.
"I personally think it will be a great thing. People are saying 'what are these people like?' but they said that about me when I took over. I was Ken Richardson's stooge for two years.
"The Doncaster psyche is always like 'hmm, no'. But why shouldn't we have our day in the sun? Why shouldn't we be in the Premier League? With £40 million you'd have a chance wouldn't you?
"I've made no secret of the fact I'm absolutely for it. There's hardly a queue of people wanting to invest in football clubs and for someone to want to invest big in Doncaster Rovers, I think it's a once in a lifetime opportunity.
"At the moment we're struggling to compete financially in the Championship. We've got a decent side and I think we'll do okay but it'd be lovely to see us near the top fighting it out to get in the Premier League.
"The quality of players that were lined up would make a significant difference."
