Inter Milan went top of the table with a "perfect" 3-0 victory over Sampdoria last night.
"We went on to the pitch with the desire to do better than in other games. I believe that perfection is difficult to come by, as there will always be mistakes to find. But we have improved a great deal and remained compact at all times."
Luis Figo struck for Inter, while Zlatan Ibrahimovic scored another double and Mancini added: "Is he in the running for the Ballon d'Or? I don't know. Usually those who win it are the ones who go all the way in the Champions League after taking the title. He has time."
It is a definite confidence booster ahead of Saturday night's top of the table showdown between Inter and Roma.
"I hope to win," added Mancini. "I didn't rotate the squad, though, today I only chose the team I thought could beat Sampdoria."
