Dunphy believes City have some way to go to be considered the best English club of the Premier League era.
"I'd put about 10 teams ahead of them, they're nowhere close to being the greatest team of all time in England, or anywhere else for that matter," Dunphy told RTE 2fm's Game On last night.
City won their third Premier League title in spectacular style, with a gap of 19 points to second-placed Manchester United. However, Dunphy believes this is more a reflection on the quality of their opponents.
"You have to look at the state of the other clubs that were contending, starting with Man United perhaps. You could look at Tottenham, Chelsea, Arsenal. All of them have problems, very serious problems in Arsenal's case, in Chelsea's case."
