Edin Dzeko's first-half header lifted Manchester City three points clear at the top of the Premier League football table with a gritty 1-0 victory at bottom club Wigan Athletic.
After dominating possession with their trademark swift passing, City's breakthrough came in the 22nd minute when David Silva floated a free kick into the box which Dzeko nodded past Wigan keeper Ali Al Habsi.
City moved to 51 points from 21 games, three ahead of champions Manchester United.
Third-placed Tottenham Hotspur, who visit City next Monday are a further two points behind.
Wigan stayed bottom of the table with 15 points while City travelled home with the type of functional win United managed so often last season on their way to a record 19th league title.
