United drew the first blood courtesy England Striker Wayne Rooney's 29th minute goal. But the joy was short-lived as in the 54th minute of the match, David Luiz scored the equaliser for Chelsea.
And then came the controversial second goal for Chelsea, which according to Machester United's manager Sir Alex Ferguson was too 'soft'. Chelsea's Frank Lampard scored a goal of a penalty earned when Chris Smalling tripped Yuri Zhirkov.
The victory ensured that Chelsea continued their unbeaten run against Manchester United at their home venue since 2002.
Speaking at a post-match interview, Ferguson told Sky Sports, "It was a great performance by us. We didn't deserve that...It's three years in a row the referees' decisions have changed the game."
He also added, "I'm proud of my players tonight, they've endured a lot of decisions against them and they've done their best."
