In London, William Gallas scored an injury-time equalizer for Arsenal to draw 2-2 with Manchester United and stay unbeaten in the Premier League.
Gallas' shot crossed the line before it was pushed out by Manchester United goalkeeper Edwin van der Sar, with the linesman awarding the goal.
"The referee interrupted the game and I thought he had given a free kick against us for offside, so I had a surprise because the ball was in," Arsenal manager Arsene Wenger said.
Cristiano Ronaldo scored in the 83rd minute to give Man United a 2-1 lead. Gallas had scored an own-goal in first-half injury time before Arsenal levelled through Cesc Fabregas in the 48th.
Manchester United led 1-0 when striker Wayne Rooney received a cross from Wes Brown and his shot from close range was deflected in off Gallas' right arm.
Gallas had his team's best chance in the first half, a header which was saved by the legs of Van der Sar in the 36th.
Fabregas scored his 11th goal in 16 games to make it 1-1. Emmanuel Adebayor had a shot saved by Van der Sar and Bacary Sagna crossed the loose ball for Fabregas to side-foot inside the corner.
Fabregas' 58th-minute free kick was saved by Van der Sar, while Rooney headed wide in the 64th.
Arsenal stays top on goals scored with 27 points -- the same as United -- but the Gunners have played one game less.
