This season, the turnaround in City's fortunes has been spectacular.
From the arrival of Mark Hughes as manager, Sheikh Mansour as owner and Brazilian Robinho as the most expensive player ever to hit these shores.
Dunne said: "I remember it all happening on deadline day.
"I was back home in Ireland watching the television with eight friends and suddenly it all went crazy.
"It wasn't just the takeover. The news suddenly flashed up that we had bid for Robinho and we just said 'This is ridiculous'.
"Yet by midnight we had actually signed him and the new owner was really showing his intent."
In eight years with City, Dunne has pretty much been on a non-stop rollercoaster ride.
He said: "There have been so many false dawns. That is probably the worrying thing for the fans at the moment - that this might go wrong.
"But I cannot see how this won't work. We have a great manager in Mark Hughes, who convinced me to stay, and now we have the backing to take us into the top four."
