United go top as Chelsea slip
Manchester United scaled the Premier League summit for the first time this season after Robin van Persie scored against his old club Arsenal in a victory more comfortable than the 2-1 scoreline suggested.
Van Persie's early effort and a second-half header from Patrice Evra saw United leapfrog Chelsea after the London side conceded a late equaliser in a 1-1 draw at Swansea City.
Victor Moses put Chelsea ahead just past the hour in south Wales but Pablo Hernandez grabbed a point in the 88th minute.
United are a point clear of the European champions with 24 from 10 games while Manchester City missed the chance to move level on points at the top after drawing 0-0 at West Ham United.
