Manchester United overcame a floodlight failure to win 1-0 at Fulham through a late Wayne Rooney goal on Saturday as Alex Ferguson's side went 10 points clear at the top of the Premier League.
An open first half saw the woodwork rattled four times, with Bryan Ruiz hitting the post for Fulham, while Patrice Evra, Fulham defender Brede Hangeland and Rooney all sent the ball against the frame of the hosts' goal.
A floodlight failure in the 43rd minute plunged Craven Cottage into darkness and forced the players off the pitch, but they returned to complete the first half after the lights came back on.
Rooney netted the winner in the 79th minute, haring down the inside-left channel and steering the ball into the bottom-right corner to send United well clear of second-place Manchester City, who host Liverpool on Sunday.
Earlier in the day, new signing Moussa Sissoko completed a second-half brace with a last-minute winner to give Newcastle United a 3-2 victory at home to Chelsea that prevented the visitors from making ground on the top two.
After Jonas Gutierrez put Newcastle ahead in the first half, Chelsea hit back through fine goals from Frank Lampard and Juan Mata to take a 2-1 lead, but Sissoko equalised in the 68th minute before driving home his late winner.
"I don't need to say anything because his performance said it all," said Newcastle manager Alan Pardew of Sissoko.
Defeat left Chelsea six points behind City and 16 points shy of Manchester United.
"There were too many mistakes," said Chelsea interim manager Rafael Benitez.
Arsenal left it late to beat Stoke City 1-0 and move to within a point of the Champions League places.
Substitute Lukas Podolski settled the game in the 78th minute with a low free-kick that deflected off Geoff Cameron to wrong-foot goalkeeper Asmir Begovic.
At Goodison Park, Marouane Fellaini headed in an injury-time equaliser to earn Everton a 3-3 draw in a breathless game at home to Aston Villa, who once again failed to defend a lead and remain firmly entrenched in the bottom three.
Meanwhile, on-loan Liverpool striker Andy Carroll scored only his second goal of the season to give West Ham United a 1-0 win at home to Swansea City.
Adel Taarabt had a second-half penalty saved as Queens Park Rangers were held to a 0-0 draw by Norwich City that left them six points from safety and four points adrift at the foot of the table.
