Sergio Aguero scored a hat-trick as Manchester City produced a rampant display against Wigan to lead the Premier League.
City were well on top and had chances before Aguero opened the scoring on 13 minutes by shooting into the corner from David Silva's cutback.
Carlos Tevez had a tame penalty saved and Micah Richards and Vincent Kompany hit the woodwork.
But after the hour mark Aguero tucked in twice to seal victory.
Both the Argentine's second-half goals looked simple in their execution, after he was put clear by Samir Nasri and Silva, but in scoring his fifth and sixth goals of the season, Aguero again underlined his class.
The 23-year-old also signalled that any continued problems with Tevez would have little impact at the club, during a week when quiet has been hard to come by.
Tevez, who was making his first Premier League start this season, was at the heart of much of City's endeavour, despite being stripped of the captaincy this week.
And with Roberto Mancini's side now having scored 15 goals in four games, the display was the perfect way to put football back on the agenda after chief executive Garry Cook resigned following claims he mocked Nedum Onuoha's mother.
On a balmy afternoon with Tevez replacing Edin Dzeko in attack, City were into their stride from the beginning and should have been out of sight by half-time.
Adam Johnson and Silva both went close early on and even Joleon Lescott inadvertently deflected Kompany's header over, before Tevez helped create City's opener.
The Argentine fed Silva, who in turn cut the ball back to Aguero, with City's newest South American striker tucking into the bottom corner.
Tevez could then have capped his return to the side with a goal after Silva was upended in the penalty box, but his spot-kick was poor and Ali Al-Habsi saved to his right.
In between those events, Franco Di Santo got on the end of Maynor Figueroa's through ball, and with Joe Hart stranded in no-man's land, the keeper was relieved to see the ball bounce past the post.
But City were dominant and Richards should have scored when latching onto Tevez's through ball, but the England defender hit the underside of the bar.
New City skipper Kompany then thumped a header from a corner against the post, and when Richards smashed the rebound across goal, somehow Lescott missed from two yards.
There were countless other chances but while the scoreline remained at 1-0 Di Santo caused some nervous moments in the hosts' defence.
Although Hart also looked shaky when he failed to grasp Hugo Rodallega's effort after a fine run by Victor Moses early in the second half, it was not long until City finally yielded the rewards their superiority deserved.
Tevez was replaced by Nasri just after the hour and within two minutes the former Arsenal midfielder had set up City's second goal.
Silva was involved again, as his drag-back teed up Nasri, and the Frenchman's poke set Aguero through for his fifth of the season.
That soon became six when Silva had acres to watch his team-mates' angled run, and Aguero simply slotted past a helpless Al-Habsi to seal the points.
Coming into the game Wigan had an unbeaten run of seven games going back to last season, but they had little chance of maintaining that record.
City, meanwhile, make their Champions League debut on Wednesday, and based on this evidence their opponents - Napoli - will have plenty to consider.
