Sergio Aguero hit his first hat-trick in English football and then insisted the team's success comes before personal glory.
The £38million signing was in stunning finishing form as Wigan were swept aside 3-0, and the Argentinian has already struck six goals to keep him on the coat-tails of the top flight's leading scorer Wayne Rooney.
Aguero told City TV: "It was great to get the three goals but the most important thing is that we keep winning. A hat-trick is good but for me the most important goal was the first one, as we needed to score."
Aguero could have had even more - he had looked keen to take the penalty compatriot Carlos Tevez missed, and went close on several other occasions.
Aguero's goal-scoring secured him the sponsors' man-of-the-match award but for many at Eastlands it was Spanish midfielder David Silva who ran the game in which City were hugely dominant - and for manager Roberto Mancini far too wasteful.
Mancini said: "We had 15 chances in the first half and we scored only one goal - this is a problem because the game can change any moment.
"Next time it's better if we close out the game in the first half.
"We need to improve because we have started the season very well but the season will be long. If we want to arrive at the end of the season still at the top we need to improve."
Mancini said he was pleased with Tevez' performance despite the Argentinian, who had seemed odds on to leave City in the summer, not being fully fit.
"Carlo is not 100% at the moment but I am happy for him because for me he played very well with Sergio, he missed a penalty but this can happen - usually he scores," said Mancini. "It was important for him to start, to play and to play well and maybe in two or three games he will be 100%."
