Chelsea remain top of the EPL table after coming from behind to inflict the first Premier League defeat of the season on Tottenham.
The Blues who were second best in the first half fell behind to Christian Eriksen's superb strike.
However, Pedro matched Eriksen goal with a timely curled equaliser just before halftime.
Victor Moses continued his brilliant recent by scoring the winner from close range after Costa played the ball across the face of the Tottenham’s goal. This goal which happens to be the winning goal leaves Chelsea a point above both Liverpool and Manchester City.
Spurs' miserable record at Stamford Bridge has therefore been extended to 30 games without a win since February 1990.
