Antonio Conte and Thomas Tuchel have clashed on the touchline after the Tottenham boss celebrated in the face of his counterpart - before both men were sent-off after a confrontation at full-time.
Conte is back at his former home, having led Chelsea for two seasons, but with his loyalties firmly with the north Londoners. A trip to Stamford Bridge is an early test of Tottenham's credentials after an impressive summer of recruitment which has seen them tipped to usurp their rivals.
Chelsea took the lead in the first-half through Kalidou Koulibaly and have largely dominated in west London. Tottenham, despite being second best, have remained in the contest and were able to equalise through Pierre-Emile Højbjerg, who slotted home from 20 yards.
