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 said: "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."
Mancini said he was pleased with Tevez's performance despite the Argentinian not being fully fit.
"Carlo is not 100pc 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 100pc."
Wigan boss Roberto Martinez said it was too soon to start comparing them to Barcelona.
He said: "Only time will tell, Barcelona, when they started with Frank Rijkaard had little flashes like Manchester City showed. In three years down the line you will be able to compare them.
"Nobody can be compared to Barcelona yet, you have to win many titles together first.
"We all know they are world-class players but what Roberto Mancini has achieved is making them play as a team and it is a joy to watch."
Martinez claimed however his players had shown City too much respect.
He added: "We played the occasion too much, we played their squad, when we only had to focus on the 11 players in front of us."
