City came from behind to beat Chelsea 4-2 at Stamford Bridge.
Mancini told Sky Sports: “Wayne Bridge played very well, very concentrated.
“I think that today we played with a fantastic team spirit and because of this we won, without it it would be difficult.
“Chelsea are a fantastic team, for many years they have played in the Champions League, and it was a difficult game.
“We performed very well, we attacked and counter attacked well.
“The most important thing is the three points for the mentality, for the spirit, for the future, and for the table.”
