Juan Mata scored two second-half goals as Chelsea came from behind to beat Tottenham in a thrilling London derby at White Hart Lane.

The Blues dominated the first half and took a deserved lead into half-time through Gary Cahill's superb volley, reports the BBC.

Spurs took back control when William Gallas and Jermain Defoe struck.

Mata scored from the edge of the area to level and converted Eden Hazard's pass for the winner before Daniel Sturridge added a flattering fourth.

It was a disappointing result for Tottenham manager Andre Villas-Boas in his first game against Chelsea since being sacked by the Blues, who temporarily stretch their lead at the top of the Premier League to seven points, with second placed Manchester United playing Stoke in the later game.
