Rooney double keeps United on top
	London: Wayne Rooney scored twice as Manchester United came from behind to beat Sheffield United 2-1 and stay three points clear of champions Chelsea at the top of the Premier League in Saturday. Chelsea beat West Ham United 1-0 at Stamford Bridge where Geremi scored the only goal with a 22nd-minute free kick to stretch Chelsea's unbeaten home league run to 51 matches. Arsenal, though, who moved into third place last week, lost ground after being held to a 1-1 draw at home by Newcastle United. They dropped back to fourth after Portsmouth beat Watford 2-1 to move above them. United, who have won their last seven successive league games, top the table with 34 points from 13 matches, Chelsea have 31 from 13, Portsmouth 23 from 13 and Arsenal 22 from 12. Sheffield United and Manchester United, meeting in the league for the first time for 13 years, played out a fiercely contested, full-blooded match at Bramall Lane where the home side struck first. Keith Gillespie, who began his career at Manchester United and played a handful of games before leaving in 1995 as part of the deal that took Andy Cole from Newcastle to Old Trafford, opened the scoring with a diving header after 13 minutes. But 17 minutes later the leaders were level with Rooney scoring his sixth league goal of the season and the striker, who scored England's goal in the Netherlands in midweek, secured United the points with a 75th minute winner. Rare Goal At Stamford Bridge, Geremi scored his first goal since October 2005 with a superbly taken 22nd-minute free kick awarded after Danny Gabbidon fouled Didier Drogba.
