The City chief saluted Mario Balotelli (here is the "non celebration" with folded arms), who bagged a penalty opener in a 3-1 defeat of previously-unbeaten Newcastle.
But Mancini claimed his money-laden leaders must improve when they try to clinch a Champions League knock-out spot with victory at Napoli tonight in Italy.
And Micah Richards heightened the mystery over his England exile with a fine goal worthy of his excellent performance.
Mancini drooled over Balotelli's dead-ball finishing.
He said: "With the penalties Mario is fabulous. It is impossible that he misses. I don't know why. He shoots very well.
"Mario is a very important player for us. He is a great player and is getting better and better.
"I am trying to help him because I don't want him to waste his talent and to make sure he can become the player he can become.
"The rest is down to him and he is doing very well."
Magpies boss Alan Pardew rated City "the best side we have played by some distance".
