Ross Barkley scored a late equaliser as Chelsea drew 2-2 with Manchester United - leading to a touchline altercation which saw Jose Mourinho dragged away from a flare-up in the mouth of the Stamford Bridge tunnel.
The former Blues boss has not won at his former ground since taking over at United and he was involved after the home bench erupted in celebrations at the late leveller.
The visitors had looked on course for a rare Premier League win in west London as an Anthony Martial brace cancelled out Antonio Rudiger's opener.
However, Barkley slammed in the last meaningful kick of the contest to secure a point, with all eyes then drawn to a spat between Mourinho and Chelsea's second assistant coach Marco Ianni.
