Chelsea welcomed former Blues boss Antonio Conte back to Stamford Bridge for the first time as a league opponent, and got the better of Tottenham once more after their Carabao Cup success.
The teams went in goalless at the break, after Harry Kane thought he had put the visitors ahead only for his goal to be chalked off for a push on Thiago Silva.
Chelsea came out stronger in the second period, with Hakim Ziyech's stunner putting the home side in front and Silva adding a quickfire second when he headed home a free-kick.
