Hosts make it four wins in four to go to the top of the Premier League table after Roberto Martinez's side failed to contain the Argentina forward
A Sergio Aguero hat-trick wrapped up the three points to leave Roberto Mancini's men at the top of the Premier League table with 15 goals in their opening four games.
The Italian gave Carlos Tevez a starting berth in place of the Premier League's leading scorer Edin Dzeko with the Argentine looking to reestablish his reputation with the Eastlands faithful following a summer of transfer speculation that only served to damage his reputation. Another recent arrival, Samir Nasri, started on the bench along with Dzeko.
Latics boss Roberto Martinez was equally hesitant with his potential debutants, leaving Spanish winger Albert Crusat on the bench as well as Patrick van Aanholt and Shaun Maloney out of the squad completely.
City started brightly, and not long after Adam Johnson blazed over the bar, the home team had its lead. David Silva, who has been in irresistible form, played in Aguero after a fine bit of skill and the former Atletico Madrid man drilled home.
The home team continued to press the issue and had a chance to double the scoreline when Adrian Lopez hauled down David Silva in the area, resulting in a penalty. Carlos Tevez was given the chance to make it two from the spot but tamely scuffed his effort into the arms of Al-Habsi.
Wigan, still a goal down, however, was forced to open up more, though in doing so exposed itself to City's counterattacks, though Johnson, Aguero and Micah Richards all missed chances to add to their team's advantage. The dynamic of the game changed very little as halftime approached, with City creating a series of good chances, but failing to finish them.
The visitors seemed willing to make the most of City's profligacy and came out in the second period with impressive movement going forward and Ben Watson was unlucky to not find his way in behind goal.
It was an impressive showing of endeavor from the visitors but any chance they had of getting back into the game was soon quashed by Aguero. The Argentine finished off some sublime build-up play from Toure, Silva and substitute Samir Nasri with a neat finish past Al-Habsi.
With the ruthlessness of true title contenders, the hosts turned the knife with another shortly after. It was Aguero once again, profiting from a magnificent ball from Silva to all but end the contest. It was a performance worthy of a hat-trick from the Argentine, who has taken his tally to six goals in four City appearances.
