KEY POINTS:
Unbeaten Arsenal stretched their lead in the Premier league to five points after a 2-1 win at Aston Villa while Chelsea beat West Ham United 1-0 to overhaul Manchester United and go second.
First-half goals from Mathieu Flamini and Emmanuel Adebayor cancelled out Craig Gardner's 14th-minute strike and Arsenal, dominant in the first half, survived concerted pressure from the home side in the second to take all the points.
Chelsea midfielder Joe Cole sank his former club, rounding Robert Green in the 76th minute to chip right-footed into the top of the net.
Chelsea, now unbeaten in 70 home league games at Stamford Bridge in a run stretching back to February 2004, have 31 points from 15 matches.
Steve Bruce's return to the JJB Stadium as Wigan manager started in the worst possible fashion, with Brazilian Geovanni putting Manchester City ahead in the first minute before Paul Scharner equalised with a diving header in the 25th.
Paul Jewell, who kept Wigan up at the end of last season, started his reign at bottom club Derby County with an agonising 1-0 defeat at Sunderland.
Anthony Stokes scored the 90th minute winner with an overhead kick from the right side of the box that lifted Sunderland out of the bottom three and up to 14th place.
"It's a kick in the teeth for us ... ," Jewell said.
"We know we are up against it but the lads gave me everything they had today ...
"We're disappointed but I wouldn't say we crumbled."
Middlesbrough replaced north-east rivals Sunderland in the relegation zone after a 1-1 draw at Reading.
Everton, who thrashed Sunderland 7-1 last week, were unable to repeat their heroics and drew 0-0 at Portsmouth, while Blackburn Rovers hammered suffering Newcastle United 3-1 at Ewood Park.
While Arsenal provided Villa with a masterclass in passing football in the first half, they will have felt fortunate to leave Birmingham with all three points after Martin O'Neill's side dominated the second.
