Chelsea defeated Hull 2-0.
Chelsea will sit on top of the Barclays Premier League table at least for 24 hours after their away victory over Hull City.
Goals from Eden Hazard and Fernando Torres, both in the second half, ensured an away victory for the Jose Mourinho coached team.
Chelsea now have 46 points from 21 games, one point and one game more than Arsenal who play on Monday away to Aston Villa.
The London side could be leapfrogged on Sunday if Manchester City defeat Newcastle.
