Arsenal surged to the top of the Premier League with Samir Nasri scoring twice in their 2-1 win over Fulham as Chelsea's dire run continued with a 1-1 home draw against Everton on Saturday.
French international midfielder Nasri showed great footwork for both his goals at The Emirates as Arsenal moved to 32 points.
Chelsea, who have taken just five points from their last six league games, led with a Didier Drogba penalty but Everton, who took four points from the champions last season, grabbed a deserved late equaliser through Jermaine Beckford. Chelsea has just one win in the last six league games and walked off the pitch to boos.
The champions have 30 points, one behind Manchester United whose game at Blackpool was frozen off. Manchester City are fourth on 29 after they ended Bolton’s run with a 1-0 victory courtesy of an early Carlos Tevez goal.
City wasted a number of chances to increase the lead and then had Aleksandar Kolarov sent off in the second half, but Tevez's fourth-minute goal was enough to secure the win.
David Silva hit the crossbar for City in the second half, while Bolton nearly equalised in the 71st following an error by goalkeeper Joe Hart, but Vincent Kompany cleared off the line.
Fifth-placed Tottenham lost ground when they could only draw 1-1 at Birmingham City while Blackburn Rovers, thrashed 7-1 by Manchester United last week, bounced back impressively by beating Wolverhampton Wanderers 3-0.
