Thomas Tuchel and Antonio Conte were both sent off after two physical clashes during Tottenham's draw with Chelsea at Stamford Bridge.
The two managers squared off following Pierre-Emile Hojberg's equaliser after Tuchel suggested Kai Havertz was fouled in the build-up, before ill-scenes could be seen after the full time whistle.
The two were eventually shown red cards by referee Anthony Taylor as the latest edition of what has become a sour London derby finished 2-2.
The first clash was triggered by a debate on whether Pierre-Emile Hojberg's goal should have stood because of a suggested foul by Rodrigo Bentancur on Kai Havertz, which wasn't given by Taylor.
