After Mancini had bought an advert in the Manchester Evening News to thank the City fans for their support, a group of fans returned the gesture in Italian newspaper La Gazzetta dello Sport.
"There has been a great feeling with the City supporters. We won three trophies in three and a half years at a club that had not won for 40 years and their affection is proof of the strong bond we have created," he told the paper.
"We also succeeded to win 6-1 at Old Trafford against Manchester United. Now the club will therefore continue to do important things."
